On the 15th of July 1662 a Charter granted by King Charles II 
passed the Great Seal incorporating, under the name of ' The 
Royal Society ', a company of eminent and enthusiastic men who 
for some years had been prosecuting the study of Natural Science, 
or, as it was then termed, Experimental Philosophy. This date 
has accordingly been reckoned to be that of the birth of the 
Society as an organized association. The approach of the 250th 
return of the day suggested that the event was one which might 
appropriately be marked by some special form of commemoration. 
Hence, early in the year 1911 the President and Council of the 
Society determined to make it the occasion of a Celebration 
which should be held at a time as near as might be found 
convenient to that of the Society's birthday on 15th July 

As an appropriate permanent memorial of the occasion two 
volumes were undertaken to be prepared and published — (1) a new 
edition of the ' Record ' of the Society and (2) a facsimile repro- 
duction of the pages of signatures of the Fellows in the Charter- 
book, from that of the Royal Founder down to those entered in 
the summer of 1912, 

The ' Record ', as revised, re-arranged, and enlarged, is intended 
to give an account of the foundation and early history of the 
Society with the text of all its Charters; its Statutes with their 
variations down to the present time, the Society's various Trusts, 
lists of its Benefactors, its Presidents and Officers and its Medal- 
lists and Lecturers, with an account of its Library, Portraits, 
Busts, and Medals, likewise full details regarding the existing 
Committees and the various work of the Society. The Chrono- 


logical Register of the Fellows has been thoroughly revised and 
for the first time made complete. 

The facsimile reproduction of the Signatures has been success- 
fully accomplished by the University Press, Oxford, and has been 
published in a folio volume with the title, ' The Signatures in the 
First Journal-book and the Charter-book of the Royal Society.' 
This interesting volume contains the autographs of the Fellows 
from the first founders down to the present day, and is probably 
the most extensive existing collection of the signatures of dis- 
tinguished leaders in science during the last two centuries and 
a half. Besides the pages of the Charter-book, the volume 
also comprises facsimiles of three pages of the first Journal- 
book of the Society, on which, under date 5th December 1660, 
are inscribed the autograph signatures of the original company 
of men of science and their friends and well-wishers who resolved 
to form themselves into an organized Society, and who, some 
nineteen months later, were incorporated by the King as ' The 
Royal Society '. One of the chief difficulties in the preparation of 
this facsimile volume arose in the decipherment of many of the 
signatures and the compilation of an alphabetical List which 
should give accurately the dates of admission into the Society, 
with the page of the Charter-book on which each signature would 
be found. But in the end every signature was identified, and the 
volume together with the ' Record ' were both ready for dis- 
tribution by the 13th of July, on which day the President and 
Treasurer had the honour of presenting a copy of each volume to 
His Majesty King George V, who was graciously pleased to 
accept them and to express his interest in the forthcoming 
Celebration. Copies of these volumes were subsequently sent to 
the Universities, Academies, and other Institutions that were 
represented at the Anniversary. 

The invitations to be present in London for the purpose of 
attending the Society's Celebration began to be issued in January 
1912. Each Foreign Member and a number of eminent foreign 
men of science who were not ]\Iembers were specially invited, 
and the Universities, Academies, and other learned Institutions in 
the United Kingdom, in the British Dominions beyond the Sea, 
and in all the civilized countries of the world, were each asked to

send a delegate. The illuminated Invitation was in Latin and in 
the accompanying form, with the requisite verbal variations in the 
last paragraph when addressed to individual persons. 

It was arranged that the various functions should extend from the 
evening of Monday, July 15th, to the evening of Thursday, 18th. 
The following Diary was printed and placed in the hands of the 
Fellows and visitors before the proceedings began : 

Monday, July 15th.

The foniial Celebration was held in the Rooms of the Royal 
Society in Burlington House. For the convenience of those 
attending it, an Enquiry Office and Post Office were fitted up 
in the adjoining meeting-room of the Geological Society, which 
that Society had kindly lent for the occasion, and where all the

cards of invitation, tickets, and other documents connected with 
the Celebration were obtainable. 

A number of the Clubs in the west end of London elected 
Foreign and Colonial Delegates Honorary Members during the 
time of the commemoration. A Committee of Ladies was formed 
for the purpose of providing entertainment for ladies accompanying 
delegates, at such times as they would not be present at the 
functions of the Society. The meeting-room of the Royal Society 
was set apart for the use of these ladies. The Ladies' Committee 
took care that some of their number should always be in attend- 
ance in that room at specified hours in order to render every 
assistance in their power. By wearing different coloured badges 
they indicated which of them spoke French,' German, or Italian. 
They organized visits to the Royal Gardens, Kew, and to places of 
interest in London, and some of their number accompanied the 

A Register was kept in which every Delegate was requested 
to sign his name. This collection of autographs forms an 
interesting record which will be preserved among the Society's 

The Royal Society's invitation met with a cordial reception 
aU over the globe. The great majority of the Universities, 
Academies, and other scientific Institutions sent delegates who 
presented congratulatory addresses. In cases where delegation 
was not attempted the addresses arrived by post together with 
many telegrams of felicitation. The following is a brief narrative 
of the proceedings throughout the Anniversary : 

Monday, .July 15th, 1912. 

This being the birthday of the Royal Society the President, 
Council, and Fellows assembled in the evening in their Library 
for the purpose of informally welcoming such of the Delegates as 
had already arrived in London, and settling with them some of 
the arrangements for the more formal reception to be held on the 
following day. A large proportion of visitors were present, though 
some were unable to reach liOndon in time for this meeting. 

250th anniversary 

Tuesday July 16th. 

By arrangement with the Dean and Chapter, a short com- 
memorative service was held at noon in the ancient Abbey of 
Westminster. Assembling in the historic Jerusalem Chamber, 
the President and Council of the Royal Society, in academic 
dress and preceded by the Society's Mace, followed in procession 
the Dean and clergy to the places reserved for them. Seats were set 
apart for the general body of the Fellows, for the Foreign Members, 
and for the Delegates and ladies who had accompanied them. 
The music was arranged and conducted by the organist of the 
Abbey, Sir Frederick Bridge, C.V.O., Mus.Doc. Towards the 
close of the service a short address was given by the Dean, the 
Right Reverend Bishop Ryle, C.V.O., D.D., who, at the request 
of the Society, has permitted it to be printed here. 

Address by the Dean of Westminster. 

1 Esdras iv. 38, 40, 41. Truth abideth, and is strong for ever; she liveth 
and conquereth for evermore. . . . Blessed be the God of truth. . . . And all 
the people then shouted, and said, Great is truth, and strong above all things. 

' Magna est Veritas, et praevalet.' 

' There have been times even within the memory of some who 
are gathered within these walls, when a welcome such as we have 
desired to give in this Abbey to the Members of tlie Royal 
Society on the occasion of its 250th Anniversary, would have 
received but a faint echo from the religious world of this country. 

' The perturbation which took possession of men's minds last 
century at the period of the most startling of the discoveries in 
Natural Science was wont to betray itself too often in ill-considered 
words of fear, impatience, and indignation. Nor need we wonder. 
To quote the words of John Fiske : " The men of the present day 
who have kept pace with the scientific movement are separated 
from the men whose education ended in 1830 by an immeasurably 
wider gulf than ever before divided one progressive generation of 
men from their predecessors." JNlisunderstanding, apprehension, 
and friction were the result. 


' We look back with regret upon any occasion when the cause 
of truth on any of its many sides has been compromised by the 
attitude of its defenders ; or when the spirit of charity and 
toleration has been forgotten in the wretched atmosphere of 

' Times are changed. I believe I may claim to speak in the 
name of the whole world of contemporary Christian thought, 
when in this Abbey I give expression to the gi-atitude which, as 
a rule, we clergy have little opportunity to render, for the amazing 
enrichment of human thought which has resulted from the patient 
researches of Natural Science during the past two hundred and fifty, 
and in particular during the past eighty, years. We thank God for 
the great and glorious work that has been done by the men of 
science; for the widening of human thought; for the elevation com- 
municated to the methods and ideals of study. " Science," as has 
finely been said by an eminent religious teacher in our own day — 
" science is truly a revelation. . . . Instead of the round world whicli 
cannot be moved, every star that twinkles in the sky becomes 
a fiery sun whirling through the deeps of space. Instead of the 
six days of creation, we look down vistas of time to which 
a thousand years are no more than a watch in the night. Instead 
of repeated acts of creation, we see a mighty chain of life 
stretching upwards from the sea- weeds and the sponges to — where 
shall we put a limit to all-enduring patience and all-sovereign 
goodness ? " * 

' With all humility we express our grateful obligation for the 
benefits which for a quarter of a millennium have been rendered in 
this country by the Royal Society. In no small measui*e it has 
been due to the weight of wise opinion created by its studies and 
observations, that the intellectual life of the people has emei'ged 
so far as it has from the influence of the Middle Ages. The woi'k 
of the Royal Society has tended to elevate and purify thought. 
It is untrammelled by party politics. Its studies overleap the 
barriers of race and language. They make for the peace of the 
world, as well as for the well-being of eveiy class. They con- 
tinually contribute to the promotion of Unity. Truth is one ; 
and however feebly our words may express it, yet we are convinced 

' Gwatkin, Knowledge of God, ii. 275. 


that the discoveries of Science discharge a truly prophetic office 
in making known to mankind the facts of the Universe, in which 
we beUeve we may read the record of the Will of the Supreme 
Mind. And in deepest humility we express our conviction that 
the God whose laws are discerned in evolution, gravitation, and 
the conservation of energy is He whose laws will be no less 
clearly discerned in love, forgiveness, and redemption, in the 
spiritual existence and in the gift of immortality. 

' We stand, as it were, bareheaded, while you proclaim to 
a solemnized and attentive world the wonderful mysteries of the 
Universe. You have added sanctity to the knowledge of phe- 
nomena; you have laid deep and lasting the foundations of 
accurate research ; you have quickened intellectual life with the 
enthusiasm for the investigation of truth. You bid us not stand, 
but go forward. 

' In conclusion, let me remind you, while I bring to an end this 
word of welcome to our Abbey, that we revere in this place the 
great names which are famous on your roll of distinction, and 
which are no less famous among the memorials committed to our 
keeping. Newton and Darwin, Herschel and Adams, Humphry 
Davy and AYoodward, Buckland, Lyell and .Joule, William 
Spottiswoode and Stokes and Kelvin, how varied, how illustrious 
is this galaxy of men, so simple in their lives, so potent in their 
influence ! It is not for me to speak. But I suppose we should 
not be wrong to assume that even with the light which the work 
of these great men has shed upon the pathway of the progress of 
mankind, we have only so far travelled a little way out of darkness. 
What may We not in all humility pray for and expect from 
the discoveries of Natural Science in the next two hundred and 
fifty years ? 

' That in the future, as in the past, the work of your Society 
may be blessed to the increase of human knowledge, for the good 
of our fellow creatures, and in the maintenance of just and 
charitable opinion among all classes of the community, is, I am 
sure, the earnest prayer of every man who has the fear of God in 
his heart. 

'"If Reason may not command," said Whichcote, some two 
hundred and fifty years ago, "it will condemn." And it is 


through the pre-eminent influence of the men of the Royal Society 
in the field of Natural Science, that we believe that Reason, as 
the noblest gift of God to man, will assert its unfailing and bene- 
ficent sway, never ceasing to be touched with the passionate search 
for the secrets of truth and ever fired with the love of our fellow 
creatures, and animated with the generous hope of benefiting them 
through the application of scientific discovery. Magna est Veritas, 
et praevaletJ 

In the afternoon at 2.30 the formal Reception of the Delegates 
took place in the Great Library of the Royal Society, which was 
completely filled. The Delegates were grouped according to the 
countries they represented, these countries being taken in alpha- 
betical order. After the visitors had been marshalled to the seats 
reserved for each country the proceedings began with an address 
fi'om the President, Sir Archibald Geikie, who spoke as follows : 

Address ok the President. 

' On behalf of the Royal Society, I desire to express our warm 
appreciation of the sympathetic response which has been made by 
so many Universities, Academies, and learned Institutions in all 
parts of the world, and by so many distinguished men of science, 
to our invitation to celebrate with us on this occasion the 250th 
birthday of the Society. No more striking proof than is presented 
by this assembly could be given of the reality and cordiality of 
that spirit of frank and loyal co-operation which unites into one 
great brotherhood the students of science in every land and in 
every language. We welcome you. Gentlemen, with our whole 
heart. We appreciate most sincerely the honour which has been 
conferred on the Royal Society by your presence here to-day. We 
greet the Delegates who bring to us the felicitations of some of 
the oldest centres of culture in Europe, which had become famous 
some centuries before our own Society was born. Not less fully 
do we rejoice to meet the Delegates from the younger Institutions 
in our own and other lands, who have come from British dominions 
beyond the seas, from furthest Asia and Africa, and in such numbers 
from the Great Republic across the Atlantic where tlie lamp of 
science now burns with so bright a radiance and in so many 

250th anniversary 9 

centres of growing activity. While it is a proud satisfaction to 
receive among our guests to-day leaders in science whose names 
have become honoured household words in all parts of the globe, 
the gratification is not less to find, among your number, scholars 
who represent the older literary learning, who have been deputed 
to convey to us the congratulations of the time-honoured Univer- 
sities which they adorn. To one and all we return our grateful 
thanks for your presence here at our Celebration. We sincerely 
desire that the few festal days which you are to spend with us 
may be in every way enjoyable to you, so that your impressions 
of your visit to London on this occasion may become a pleasant 
memory which you will care to cherish in the days to come. 

' Two hundred and fifty years seem in some respects no long 
span of time in the course of human history, but the two hundred 
and fifty years across which we look back to-day have been in the 
history of science a period of momentous importance, crowded 
with incident, and full of marvellous achievement. When in 
the earlier decades of the seventeenth centuiy Francis Bacon was 
so cogently insisting on the necessity of studying Nature by the 
careful observation of facts and the testing of conclusions by 
experiment, he made but slight practical impression in England. 
The seed which he sowed did not spring into life until after he 
had passed away. About the middle of the century, however, the 
spirit of eager curiosity and inquiry with regard to the world 
wherein we live, which spread over all civihzed countries, reached 
England also. Nature was still, as it had been from the earliest 
days of mankind, a vast unknown region, full on every hand of 
mystery and wonder. Even the most everyday phenomena 
presented to thoughtful minds problems for which no satisfactory 
solution had been found. The earnest desire to seek an explana- 
tion of some of these familiar phenomena at last induced a re- 
markable group of men in this country to organize themselves 
systematically for the prosecution of that experimental philosophy 
which Bacon had so longed to see pursued. The time, however, 
was not propitious, for it was one of pohtical turmoil and civil war 
in England. The studious men who desired to pursue these 
researches sought refuge from the social strife in the quiet 
investigation of Nature. They met weekly in London, where they 


discussed many and diA^erse questions in physical and biological 
science, devising and carrying into execution numerous experi- 
ments by which they tried to ascertain the nature and connexion 
of some of the fundamental processes in the economy of this world. 
When the civil connnotions drove them from their meeting-place 
in London, some of the more active and enthusiastic among their 
number sought the shelter of Oxford, where, under the hospitable 
roof of Wadham CoUege, they were able to continue their inquiries. 
' The restoration of the Monarchy in tlie early summer of the 
year 1660, which led to the re-establishment of settled order in 
the country, allowed the resumption of scientific meetings in the 
autumn of that year. With the brighter prospects of peace 
before them, the philosophers assembled once more in the 
picturesque Gresham College in the city of London, and for the 
better accomplishment of their aims they determined to form 
themselves into a definite Society with a regular organization and 
a common fund from which the cost of experiments could be 
defrayed. Had they restricted the membership of their proposed 
Society to men of science, properly so called, their number would 
hardly have exceeded two score. But with commendable fore- 
sight they took advantage of the prevalent spirit of curiosity 
regarding the secrets of Nature, and gathered round them 
a company of three times their own number comprising prominent 
representatives of the Church, of Law, of Medicine, of Politics, 
and of the Public Services. Their adherents included also men 
of letters, and it is specially noteworthy that among these were 
the foremost poets in the England of that day — John Dryden, 
Edmund A\'aller, John Denham, Abraham Cowley, WiUiam 
Hammond, and Thomas Stanley. This brilliant assemblage of 
the intellect and learning of the time soon attracted the notice and 
the active sympathy of King Charles H, who himself had his full 
share of the widespread contagion of curiosity and inquiry. He 
attended some of the meetings of the infant Society, and on the 
15th July 1662 granted to it a Charter of Incorporation with the 
name of " The Royal Society " and the definite constitution under 
which it is still governed. That date was thus regarded as the 
birthday of the Society which, after the lapse of two centuries and 
a half, we are met to-day to celebrate. 

250th anniversary 11 

' The career of the Royal Society is fully recorded in its various 
pubUcations. Its "Philosophical Transactions" and "Proceedings", 
and likewise the separate works which it has issued, form a chro- 
nicle from which the successive stages in the progress of modern 
science can be followed. The enumeration of only a few of the 
names which appear in these volumes shows that the Society has 
counted among its Fellows some of the great leaders in all branches 
of Natural Knowledge. Starting its career with a notable group of 
physicists and mathematicians, amongwhom were Robert Boyle and 
John Wilkins, it ere long welcomed Isaac Newton into its ranks, 
published his immortal " Principia", and annually elected him as 
its President for nearly a quarter of a century. The physical 
sciences have all along been strongly represented here. It seems 
but yesterday that James Clerk Maxwell's voice was heard in 
these rooms and that Stokes and Kelvin sat in the presidential 
chair. That the succession of leaders is still well maintained, the 
presence here to-day of Lord Rayleigh, Sir William Crookes, Sir 
Joseph Thomson, Sir Joseph I^armor, and many others amply 
proves. Nor have the biological sciences been less prominent in 
the work of the Society. From the early days of John Ray down to 
those of Charles Darwin, Hooker, Huxley and Lister, every branch 
of biology has been illustrated and advanced by our Fellows. 

'As Science knows no restriction of countiy or language, the 
Royal Society has from its earliest beginning cultivated friendly 
relations with fellow workers in research all over the world. The 
first list of original members includes the honoured name of the 
physicist and astronomer Huygens, some of whose gifts to us we 
still possess ; and from that time till now the Society has been 
proud to inscribe on the roll of its Foreign Members the names of 
the most illustrious exponents of science in each generation. It 
has been glad also to recognize distinction by the award of its 
medals far beyond the bounds of the British Dominions. At the 
same time the Academies and Universities of other lands have 
ever shown a generous recognition of the labours of the Fellows 
of the Royal Society, honouring them by electing them into their 
membership or by conferring upon them academic degi-ees. This 
confraternity of the commonwealth of science reaches to-day the 
climax of its manifestation in our experience, when we receive 


delegates from so many countries who by their presence here ex- 
press the sympatliy and goodwill of the various institutions which 
they represent. To these institutions, venerable and youthful, 
a formal expression of our grateful appreciation will in due course 
be transmitted. In the meantime I will conclude these opening 
remarks by again thanking you for your presence here to-day and 
bidding you a cordial welcome to the halls of the Royal Society.' 

The presentation of Addresses from the various Institutions 
represented then began. The delegations, as arranged in the 
alphabetical order of the countries represented by them, are given 
in the following hst. As it would have been impossible that the 
Addresses should be read at the meeting, one delegate from each 
country was selected who should briefly express the friendly 
feelings of his compatriots. The Addresses themsehes will be 
found in extenso from p. 31 to p. 122 of this volume.

On the evening of July 16th the 250th anniversary of the 
Royal Society was celebrated by a Dinner held in the ancient 
Guildhall of London, which was attended by 490 guests. Besides 
the representative Delegates whose names are given in the fore- 
going list (p. 13) the company included a large number of the 
Fellows of the Society, several members of the Government, the 
Ambassadors of France, Italy, and Japan, the Archbishops of 
Canterbury and York, Cardinal Bourne, the Dean of Westminster, 
the Moderator of the Church of Scotland, the Lord Chief Justice 
of England, the Master of the Rolls, the Lord Justice Clerk of 
Scotland, and representatives of literature, art, and science. After 
the usual loyal toasts the toast of ' The Royal Society ' was given 
by Mr. Asquith, the Prime Minister, and was responded to by the 
President. The ' Universities at Home and Abroad ' were pro- 
posed by Viscount Morley, Lord President of the Council, and 
responses were given by Professor Emile Picard, of the Institute 
of France, Professor Waldeyer, of the University of Berlin, and 
Professor \^''inkler, Rector of the University of Amsterdam. The 
toast of the ' Learned Societies in the Old World and the New ' 
was proposed by His Grace the Archbishop of Canterbuiy, and 
was replied to by the Marchese E. Paterno di Sessa, of the 
Accademia dei Lincei, Rome, Prince Boris Galitzin, of the 
Imperial Academy of St. Petersburg, and Dr. R. S. Woodward, 
President of the Carnegie Institution, Washington. The last 
toast, that of the ' City of London ', was proposed by Dr. Peterson, 
Principal of McGill University, Montreal ; and, in the unavoidable 
absence of the Lord Mayor of London, a reply was made by the 
Right Honourable Sir T. Vezey Strong, the previous Lord JSlayor. 


Wednesday, Juey 17th, 

The morning of this day was set apart for visits to places of 
interest in London, such as Lambeth Palace, Westminster Abbey, 
the British Museum, Bloomsbury, the Natural History Museum, 
South Kensington, and the ^^ictoria and Albert Museum. 
Arrangements were made by which the several parties of visitors 
were conducted over these and other institutions, and the chief 
features of each were pointed out by the resident officials. 

In the afternoon the Duke and Duchess of Northumberland 
gave a Garden Party at Syon House, their residence on the 
Thames, to which the Delegates and Fellows of the Royal Society 
with their ladies were invited. As the weather was brilliantly 
fine, a large company assembled in the pictin-esque grounds and 
enjoyed the summer beauty of an English park. 

In the evening a Conversazione was held in the rooms of the 
Royal Society at Burlington House, which was numerously 
attended. Among the objects of interest presented on the 
occasion attention was specially directed to the large collection of 
portraits hung on the walls of the tea-room and meeting-room. 
In the short handbook which was supplied to the company 
a brief account of each picture was given. The portraits are 
valuable not only as likenesses of eminent men who have been 
connected with the Royal Society, but not a few of them also as 
works of art. On the walls of the tea-room hang contemporary 
portraits of Francis Bacon, Isaac Newton, Robert Boyle, .John 
Wallis, John Wilkins, Christopher Wren, John Flamsteed, 
Edmund Halley, .John Locke, and other early Fellows of the 
Society. The meeting-room contains portraits of more recent 
Presidents. Among the exhibits shown on this occasion were 
the apparatus devised by IVIr. C. T. R. Wilson for making visible 
the tracks of ionizing particles of vapour condensed upon the ions 
set free along the paths ; and also some Cloud-photographs showing 
the nature of the ionization produced by diffiarent kinds of rays. Sir 
WilUam Crookes exhibited his historical collection of Radiometers 
and Otheoscopes. Mr. C. V. Boys showed his instrument for 
experimenting with rotating soap-films. Some of the historical 
relics in the possession of the Society were likewise displayed, 
including Robert Boyle's air-pump, Huygens' aerial or tubeless 

250th anniversary 2iB 

telescope, Newton's original account of his Reflecting Telescope, 
dated January 1672, and some instruments that belonged re- 
spectively to Christopher Wren, Joseph Priestley, Captain James 
Cook, and Charles Darwin. 

Thursday, July 18th. 

The arrangements for the morning were similar to those of the 
morning of the previous day. In the afternoon, the President, 
Council, and Delegates went by railway to Windsor, where, by 
the King's command, they were first conducted to St. George's 
Chapel and thence through the State apartments of the Castle, 
where the visitors had an opportunity of seeing the treasures of 
art collected by successive sovereigns of England. The whole 
company was marshalled on the terrace overlooking the gardens, 
the same geographical arrangement of the Delegates being 
maintained as at the presentation of addresses in Burlington 
House. The King and Queen then came down to the terrace, 
and the President, Treasurer, and Secretaries of the Royal Society 
were presented to their Majesties by the Lord Chamberlain. 
The Delegates were then presented in succession to their Majesties 
by the President. After the ceremony of presentation, the 
company joined the large Garden Party which their Majesties had 
invited to Windsor on the occasion, and the King and Queen, 
conversing with their guests on the way, passed to the Royal Tent. 

As the whole Celebration was to end on the evening of this 
day arrangements were made for a series of farewell dinners, 
smaller and less fonnal than the large banquet in the Guildhall, 
when the hospitality could be mingled with more general 
friendly intercourse. A number of the Fellows gave parties, at 
which Delegates and the ladies accompanying them could see 
a little of English homes. The other Delegates were entertained 
by the Royal Society Club, a dining club connected with the 
Society for some two hundred years. At these various parties much 
pleasant conversation took place, the friendships which had been 
begun on the previous days were further strengthened, and the 
Fellows of the Royal Society bade their guests farewell with the 
assurance that the Celebration had passed off as successfully as 
could have been desired. 


The various functions an-anged by the Royal Society were now 
completed, but reference should be made to the sympathetic 
action of the Universities of Oxford and Cambridge in organizing 
an additional day and inviting a considerable number of Foreign 
and Colonial Delegates, together with a few Fellows of the Society, 
to partake of the hospitality of these two ancient seats of learning. 
On the morning of Friday, the 19th, two parties, about equal in 
number, left London for Oxford and Cambridge respectively. At 
Oxford the guests took luncheon at All Souls College, with the 
Chancellor of the University, Lord Curzon, and the Warden and 
FeUows as hosts. A garden-party in the afternoon at Wadham 
was full of interest in connexion with the association of this 
College with the early history of the Royal Society. The 
Warden gave the visitors a brief address in the Lodge wherein 
the meetings of the early founders of the Society were held when, 
owing to the political troubles of the middle of the seventeenth 
century, they could no longer be held in London. At Cambridge 
similar hospitality was shown to the guests by the Master and 
Fellows of St. John's College. 

At both Universities Honorary Degrees were conferred on 
a few of the more distinguished men who had attended the 
Celebration of the Royal Society. As a permanent and interesting 
record of the visits of this day, the Latin eloges pronounced by 
the Public Orator of each University are here given. Those at 
Oxford (by Mr. A. D. Godley) were as follow :

Eum ad vos duco qui ut geologicae scientiae nullum fere non genus 
tetigit, ita in rupium praecipue et saxorum structura atque dementis 
scrutandis mirabilem peritiam atque eruditionem praestitit. Namque patriae 
suae litorum et montium formas inspiciendo ea se cognitione imbuit ut 
priscarum illarum terrae marisque mutationum velut imaginem exprimere 
potuerit : quod qui scripta eius legerit, is glaciei paulatim recedentis tractus 
et Oceani modo prolatos modo coartatos fines velut oculis praesens aspicere 
videatiir. Quid quaeritis ? nihil nisi eruditissime idem et disertissime exposuit : 
novas reruni leges tulit et probavit : quamque alii in singulis geologiae parti- 
bus diligentiam exercent hie toti illi scientiae adhibuit. Propter illud autem 
vix minorem laudem mereri videtur, quod his studiis non otio et securitate 
a ceteris curis remotum se dedit, sed curiae suae consiliis et regendae 
Universitatis negotiis distractum atque occupatum. 

Itaque cum nemo huius temporis in ea quam profitetur scientia cum maiore 
laude sit versatus, — id quod insigne illud Wollastonianum nuper ei a doctis 
viris collatum testatur, — praesento vobis Waldemarum Christophorum 
Broggeu, Mineralogiae et Geologiae Professorem in Universitate Christianiensi, 
Rectorem eiusdem Universitatis, ut admittatur ad gradum Doctoris in Scientia, 
honoris causa.

Quod in antiquiore orbis terrarum parte a viris magni nominis iam est factum 
hie quem videtis in America cuius reipublicae civis est primus efFecit. Nam 
cum alii geologistae aliis scientiae suae partibus se dederint, hie illuc potissi- 
mum incubuit ut quaenam fuerint ea saecla animantum exquireret quae terras 
nondum in s|)eciem quam videmus informatas colebant : vestigia eorum 
e remotissima antiquitate conservata et inclusas ipsis rupibus reliquias 
enucleavit et in lucem produxit : unde nos modo monstroruni magnitudinem 
miramur modo notorum hodie animalium fontem atque originem agnoscimus. 
Quibus rebus inveniendis nmltuni laboris suscepit : iinmo in ipsa Patagonia, 
qua terrarum regione nihil potest esse ab humanitate seiunctius, tres continuos 
habitavit annos. Nemo tenebras et crepuscula mundi latiore visu amplexus 
est, nemo reperta in rationum formam prudentius composuit. Haec ut 


doctorum viroriim consensu ita praecipue Geologicae nostrae Societatis iudicio 
eomprobantur : namque ea singular! honore et praeinio ingeniosissimum 
hominem nuper omavit. Quare praesento vobis Willelmum Bereyman Scott, 
Geologiae et Palaeontologiae Professorem Blairianum in Universitate Prince- 
tonensi, ut admittatur ad gradum Doctoris iu Scientia, honoris causa. 

WiLHELM Waldeyer, University of Berlin. 

Quid est dignius quod ab academicis honoretur quam continuus vitae cursus 
uno tenore scientiae finibus proferendis deditus ? Hie enim quern videtis ex 
ineunte aevo in anatomiae studio elaboravit, cuius rei est hodie professor : 
annum agimus quinquagesimum ex quo primum reperta sua litteris mandare 
coeperat : neque postea uUus est secutus quin idem comnicntariis et libellis 
edendis industriam suam atque eruditionem indicaret. In quo temporis spatio 
permagnam rerum varietatem scribendo ti'actavit : modo ovorum partum et 
generationem animalium, modo oculos et visus rationem studiis et investiga- 
tionibus amplexus est : vix ullam denique quaestionem quae modo ad corporis 
humani structuram pertineret intactam reliquit. Neque a doctis hominibus 
tantum haec laudantur, sed et omnibus profuerunt : multum enim qui medendi 
artem profitentur sunt huius lucubrationibus et consiliis adiuti. Praesento 
ergo vobis Willelmum Waldeyeb, Imperatoris Germanici in Medicina con- 
siliarium, Anatomiae Professorem et Anatomici Collegii in Universitate 
Berolinensi rectorem, ut admittatur ad gi-adum Doctoris in Scientia, honoris 

Peter Zeeman, University of Amsterdam. 

Hominem ingeniosissimum et multum experimentis ausum vobis praesento. 
Et quoniam in hoc doctorum virorum consessu loqui posse mihi videor 
liberius, quae praecipua fuerit eius famae causa paucis (advcrtite) docebo. 
Nam cum ignis ardentis lumen per vitrum lineis distinctuni ita transmitti 
sciatis ut non omnes lineae sed secundum eius rei qua utitur naturam aliae 
alias immisso lumine fulgeant : hie si vim magnetoelectricam igni adhibueris 
commixtos una omnes spectri quod vocant colores in singulis lineis apparere 
experiendo demonstravit. Hoc repertum niaximi momenti ab iis haberi quibus 
cura est primordia rerum quali natura praedita constent investigare, omnes 
necesse est agnoscant. Itaque cum hie non modo in lucis ratione elaboraverit 
verum etiam ad mundi totius naturae cognitionem multum contulisse videatur, 
magnum inter omnes physicistas nomen et laudem consecutus est : neque est 
quisquam dignior quem titulo aliquo hoc praesertim die ornemus. Praesento 
igitur vobis Peteum Zeemak, Physicae Professorem in Universitate Amstelo- 
damensi, ut admittatur ad gradum Doctoris in Scientia, honoris causa.^ 

' Dr. Gabriel Lippmann, For. Memb. R. S., President of the Academy of Sciences of 
Paris, was to have been inchided among those who received Honorary Degrees, but the 
sudden death of Professor Poincare recalled him at once to France.

The following are the speeches delivered by the Public Orator 
(Sir John Sandys) in welcoming the Delegates, on their visit to 
Cambridge, and in presenting to the Chancellor (Lord Rayleigh) 
the several recipients of honorary Degrees : 

In ipso limine laiidationum nostrarum, Societatis Regalis tot hospites illustres, 
post sacra saecularia feliciter acta, Cantabrigiam hodie invisentes, Academiae 
totius nomine iubemus salvere. Ununiquemque igitur vestrum salutat et 
Baconis et Newtoni et aliorum in scientia naturali aut dim aut nunc insig- 
nium virorum Universitas. Dum tot scientiarum inter se diversarum cultores 
illustres e tot orbis terrarum partibus ad litora nostra atque adeo Academiae 
nostrae ad nemora hodie advectos intuemur, denuo nobis rata esse videntur 
Vetera ilia prophetae verba: — 'plurimi pertransibunt, et multiplex erit scientia.''^ 
Tot advenarum illustrium e numero placuit Senatui nostro nonnullos, gentium 
inter se diversarum legates, scientiarum inter se diversarum antistites, velut 
exempli causa, titulo nostro decorare, qui honos, vestrum omnium praesentia 
illustratus, vestrum omnium, ut speramus, benevolentia comprobabitur.

clari, Societatis Regalis baud ita pridem Praesidis, vestigia secutus, stellas, 
quae inerrantes vocantur, diligenter observavit, et spectri (ut dicitur) auxilio, 
earum motus aut recedentes aut appropinquantes accurate computavit. Idem, 
cum collegis optimis consociatus, stellas duplices atque etiam multiplices pluri- 
mas detexit ; siderum denique illorum praesertim, quonuii in aiTe helium inesse 
comprobatum est, primus tarditatem quandam motus demonstravit. Astro- 
nomo autem nostro, viro impigro, viro acerrimo, tarditatem mentis nemo 
exprobrabit. Etenim, talium virorum auxilio, 'caelum ipsum petimus,' non

quadraginta scientiam chemicam experimentis suis luculeuter illustravit. 
Peritis notum est hunc virum olim benzenii potissimum progeniem explorasse, 
— benzenii, quod matris baud pulchrae filiam, filiarum autem suavium et 
pulcbrarum matrem nominaverim. Notum est eundem postea corpora ex 
fluorino, elemento illo impigro, composita, penitus invostigasse ; in aliis denique 
elementis, bromio praesertim et phosphoro liquido, particularum pondera 
accuratius cxaminasse. Ceterum haec omnia scientiae ad mysteria intima

Russorum ex imperio maximo, a nobis remoto sed studiorum communium 
in vinculis vicino, ad nos venit physiologiae professor Petroburgensis, qui 
ciborum digerendorum rationem universam exploravit, his studiis officinam 
quandam dedicavit, physiologiae studiosorum scholam florentissimam fundavit. 
Ut alia omittam, quam pulchre ostendit sucos Ulos, qui cibo concoquendo 
inservimit, non modo mentis motu vario etiam ipsos moveri et mutari, sed 
etiam unicuique ciborum generi esse accommodates, atque omnibus elementis 
noxiis adversari et in contrariam partem fortiter contendere. Mentis quidem 
certamen Prudentii in carmine quodam heroico narratum vidimus ; corporis 
autem certamen, mentisque et corporis societatem intimam ab hoc viro 
celebratam audivimus. Talium virorum ex studiis Comelii Celsi praecepto

ad nos perlatus est scientiae physicae in Universitate Berolinensi professor, qui, 
luce cotidiana non contentus, etiam lucem illam, quae oculorum aciem fugit, 
assidue exploravit. Lucem quidem universam ex undis constare electricis, 
rationibus exquisitis ductus, Maxwellius noster olim praedixit; idque et sui 
ipsius et aliorum experimentis postea prorsus comprobatum est. Hie autera, 
rem ipsam denuo aggressus, placitis Maxwellianis maxime congruus, lucis 
undas longas est dimensus, illis quidem multo longiores quae erant antea 
cognitae, sed illis aliquanto breviores quas vis electrica per artem adhibita 
generare potuit. Sed, inter has duas undarum varietates penitus exploratas, 
iam restat intervallum perbreve, quo sine dubio (fortasse per hospitem nostrum) 
propediem expleto, Maxwellii nostri doctrina universa erit patefacta, et, inter 
tot rerum naturae miracula, etiam lucis leges melius cognoscentur. Dixit 
olim Miltonus noster, 'Lux sacra,-salve, prima progenies Dei';^ et tu, salve,

HocHGEEHRTE Gesellschaft ! Gerechtcr Stolz erfiillt unsere Seele, wenn 
wir die En-ungenschaften auf dem Gebiete der Naturwissenschaften betrachten. 
Von den geheimnisvollen V^orgiingen in der Natur liegt ein grosser Teil 
enthiillt vor unseren Augen. Wir verstelien nicht nur die grossartigen 
Vorgange, die der Himmel uns darbietet, wir lionnen sogar die Bewegungen 
der unsichtbaren Atome beschreiben. Bis zu den Grenzen der Sichtbarkeit 
kcinnen wir noch das organische Leben verfolgen, das so lange ungesttirt das 
Dasein der Menschen gefahrdete. Unziihlige praktische Erfindungen waren 
die Folge der wissenschaftlichen Errungenschaften, Erfindungen, welche fiir 
das Behagen, aber auch fiir die Gesundheit der Menschen von hochstem Wert 
sind, Erfindungen, mit denen wir Raum und Zeit besiegen. Die Erforschung 
der Natur war aber auch ein grosser Gewinn fiir die moralische Ilebung des 
Menschengeschlechtes, sie allein war es, die die Menge aus dunklem Aberglauben 
befreite, die solchen Verirrungen wie Astrologie, Alchemie usf. ein Ende 
setzte. Allergrossten Dank sind wir daher den Miinnern schuldig, die durch 
ihre Forschungen dieses Emporbliihen der Wissenschaft erzielten. Aber 
wenn es auch seit jeher nicht an hervorleuchtenden Geistem fehlte, die 
Kometen gleich Licht in die Finsternis strahlten : die neue Richtung brach 
sich erst Bahn durch vereintes Streben. Als beim Untergang der Scholastik 
in den Menschen aUmiihlich die Erkenntnis aufdanimerte, dass das Studium 
der Natur vor allem geeignet ist, unseren Geist zu befreien, da zog gerade 
in England die neue Richtung zahlreiche Schiiler an, die, indeni sie in dem 
Forschen nach Wahrheit den besten Trost fur die WiiTen ihrer Zeit fanden, 
sich zu regelmassiger gemeinsanier Arbeit verbanden und alle Teile der 
Naturwissenschaft in Angriff" nahmen. Das Anschen und die Zahl dieser 
Manner, im Anfange noch die ' Invisibles ', stieg rasch, indem ihre Mitbiirger 
den Wert ihrer Studien fiir den Foi-tschiitt der Menschheit erkannten. 
Kiinigliche Gnade erhob diese Gesellschaft 1662 zur Royal Society, ein Akt, 
welcher der ganzen Welt Vorteil brachte, indeni die Royal Society nunniehr 

' These are arranged in the same geographical order as the List of Delegates, pp. 13-21. 


(lurch 250 Jahrc iinermiidlich imnier neue Friichte des Wissens zur Reife 
brachte. Ihre Schriften enthalten die Bausteine unseres gesamten heutigen 
Wissens, durch welche sie selbst und darnach die bewundernden Schwester- 
akademien die Naturwissenschaften auf ihren heutigen Stand bringen konnten. 
Eine der jiingsten Akademien, die dem Stern der Royal Society bewundernd 
folgt, die kaiserliche Akademie der Wissenschaften in VVien, wiinscht der 
Royal Society zu der 250. Wiederkehr ihres Stiftungstages, dass sie in 
aller Zukunft ihres Bestandes sich erfreuen und fortfahren moge, eine Leuchte

Ampussimak Regali Societati Londini. Inter academias liberalium artiuni, 
quae in rerum cognitione et scientiae pervestigatione vigent, Societas Vestra 
principatum obtinet secundisque rerum proventibus antiquitus traditis ea 
incrementa cepit, in quibus perquam raro alia collegia gloriari possint. Inde 
ab ipsis cultus atque hunianitatis quasi incunabulis clari et docti viri 
Britannorum gentis societatem privatam constituerunt, quae postca tutela regis 
Caroli II Regalis nuncupata est, ut non una aliqua in re elaboraret, sed 
omnia, praecipue philosophiam, scientiae pervestigatione comprehenderet. 
Gravitate et auctoritate sua iam a primordiis domi ad magnum et honoratum 
ministerium indicis litterati et consiliarii rerum publicarum curatorum 
producta est, foris vero editiones eius ab omnibus hominibus, qui in artibus 
versantur, honorem consequuntur. Raro fit ut aliqua litterarum societas 
per tarn longum tempus sit industria singulari, sicut Vestra, cui uni omnium 
ducentesimum quinquagesimum diem natalem celebrare contigit. Qua ex re 
concludi potest Societatem Vestram munere atque officio feliciter functam 
esse, nam aliter sentire de societate, cui usus erat cum luminibus doctrinae, 
ut cum clarissimo Newton et cum viris doctis Halley, Simpson, Cavendish, 
WoUaston, Priestley, Herschel, Davy et multis aliis, baud licet. Quamobrem 
omnes viri docti de his sollemnibus gaudent, imprimis vero Croatarum 
Universitas Zagi'abiensis ex intimo corde amplissimae Regali Societati gratu- 
latur, optatque ut in scientiae pervestigatione et in posterum fortuna prospera 


utatur et quani maximos progressus in studiis faciat. Senatus acadeniicus

mus eaque soUemnia votis optimis prosequimur. Simul pia memoria illud 
recolimus, quantopere Societas vestra de cultu ac flora scientiarum, ex quo 
condita est, meruerit. Nam ilia prima tamquam dux eorum procedebat, 
quorum opera studium in omnibus scientiarum naturalium generibus renatum 
est, atque ita novas cogitandi vias per omne aevi sui spatium muniebat. 
Quando temporum iniquitate bellicisque casibus omnia ferme felicia scientias 
colendi initia in Bohemia extincta sunt, agmen virorum in doctrinis elaboran- 
tium Societas vestra iam ducebat, effecitque ut aliae similes per Europae terras

A LA SociETE Roy ALE DE LoNDEEs. — Mousieur le President, Sir Archibald 
Geikie, Associe de TAcademie royale de Belgique, Vous voulez bien porter 
a la connaissance de TAcademie royale de Belgique que la Societe 
royale de Londres, fondee, en 1645, par un gi'oupe de savants, en vue du 
progres de la science dans le Royaume-Uni, constitufe en association des 
1660, et investie le 15 juillet 1662, par le Roi Charles II, d'une Charte de 
corporation, celebrera le 16 juillet de Tannce actuelle son deux cent cinquan- 
tieme anniversaire. Vouz invitez, en meme temps, on ne pent plus confra- 
ternellement, I'Academie royale de Belgique a cette commemoration d'une si 
haute importance pour la science, en general, de tous les pays qui s'occupent 
de la culture des connaissances humaines en tete desquelles sont I'Astronomie 
et votre immortel Newton. L' Academic royale de Belgique est on ne peut 
plus flattee de cette gracieuse invitation de la Societe royale pour laquelle 
elle professe la plus grande admiration, non seulement pour ses membres si 
illustres, mais aussi pour les travaux dont ils ont enrichi la science europeenne 
pendant les deux siecles et demi ecoules de votre celebre Societe. Ce n'est 
pas d'hier, illustre Confrere, que nous apprecions la haute valeur scientifique 
de la Societe royale et sa valeur morale. Lors de son retablissement par le 
Roi Guillaume I'"", en 1816, le premier soin de TAcademie royale de Belgique 
fut de demander a la Societe royale de Londres I'echange de ses publica- 
tions avec vos celebres Philosophical Transactions. La collection que nous 
possedons de ces Transactions remonte a Tannee 1777 ; elle constitue le 
plus beau joyau de notre bibliothcque, au meme titre que les publications de 
I'Academie des sciences de Paris. C'est un tresor inestimable qui fait con- 
stamment I'admiration des savants qui y ont recours pour leurs travaux. Ils 
sont legion les membres de la Societe royale que I'Academie royale de 
Belgique a eu I'honneur de compter comme assocics depuis 1816. Et leurs 
noms sont deja entourc's parmi nous, comme en Angleterre, de I'aureole de la 
gloire : Charles Babbage, Sir John William Herschel, Pierre Barlow, Sir James 
South, Sir Edward Sabine, John Barrat, John Taylor, Robert Brown, Sir 
David Brewster, Michael Faraday, Sir Richard Owen, Sir Charles Wheatstone, 
Sir George Biddell Airy, Sir Roderick Impey Murchison, Sir Charles Lyell, 


Thomas Davidson, Charles Robert Darwin, Joseph Dalton Hooker, Andrew 
Crombie Ramsay, Thomas Henry Huxley, Lord Kelvin, John Tyndall, James 
Prescott Joule, Sir Joseph Prestwich, Arthur Cayley, James Joseph Sylvester, 
Sir William Henry Flower. D'autre part, c'est un reel honneur pour nous de 
voir encore figurer dans nos rangs Sir George-Howard Darwin, Sir James 
Dewar, Sir Edwin Ray Lankester, Sir John Murray et vous meme. Sir 
Archibald Geikie, le si distingue president actuel de la Societe royale. II 
nous est impossible. Sir, dans le cadre de cette Adresse de felicitations, de 
citer tous les travaux de votre Societe, meme les plus celebres. Et cependant 
TAcademie royale de Belgique aurait ete si heureuse d'en parler, surtout de 
ceux qui, depuis le commencement du xvii™^ siecle, ont fait progresser les 
sciences d'une maniere si prodigieuse. D'aussi celebres souvenirs et un aussi 
memorable passe, dont la Belgique, comme toute TEurope scientifique, a 
profite, sont le plus sur garant d'un avenir qui sera aussi illustre pour la 
Societe royale de Londres. L'Academie royale de Belgique souhaite a la 
Societe royale d'acquerir encore de nouveaux titres a la reconnaissance de 
Thumanite. Puisse-t-elle, a tout jamais, pour le bien de celle-ci, continuer 
a tenir avec TAcademie des sciences de Paris le sceptre de la science qui 
constitue le flambeau de la verite. Quant a Lord Lister, TAcademie, au nom 
de toute la Belgique, s'associe au deuil de TAngleterre au sujet de la mort de 
Tillustre chirurgien. Telle est I'expression des sentiments de I'Academie 
royale de Belgique, que Tun de ses membres, M. Dollo, s'est engage a vous 
apporter de notre part.

Univeesitas Hauniexsis Regali Societati S. p. D. Duo iam saecula et 
dimidium Regalis Societas ita egit, ut egregium illud dictum, quod vexillo 
suo inscripsit, semper summa cum fide exsequeretur. Eo tempore exorta, 
quo nihil fere praeter ecclesiam in lumine erat, praecipueque Naturalium 
Rerum Scientia crassa superstitionis caligine obfuscabatur, hoc sibi proposuit, 
ut novam et veram philosophiam naturalem in lucem duceret, expei'iendi arte 
fultam et ingenua inquirendi ratione procedentem. Libera, a nullius gratia 
pendens, nullo auxilio externo munita, increnientum sensu cepit et robur, 
dum socii, scientiam ipsius causa ardentibus animis amantes, infatigabili 
studendi vigore provehuntur veritatemque ex tenebris nebulisque eliciunt, 
minime eo deterriti, quod labores, quibus operam suam impendebant, saepius 


spes suas fallere nullumque profectum promittere videbantur. Procedente tem- 
pore non raro apparuit, ea quoque, quae primo aspectu vana et sterilia esse 
videbantur, uberes et inexhaustos fontes aperuisse. Quod vere dictum est, 
Anglorum nationem non victoriis terras expugnando coloniasque late per 
orbem condendo potius quam naturam suae terrae sibi subiciendo magnam et 
illustrem factam esse, quodque nulla cuiquam relinquitur dubitatio quin 
accrescens Rerum Naturalium Scientia toti generi humane immane quantum 
profuerit, Regalis Societas merito gloriari potest, tam banc patriae laudem 
quam illas communis hominum vitae utilitates magnam partem viris deberi 
quos in sociorum numero habuerit. Ingenuo et grato animo eorum beneficio- 
rum memoriam retinens, quae bonarum artium studia huie Societati debent 
quae ipsa princeps condita postea multis aliis eiusdem generis societatibus 
originem dedit et normam, Universitas Hauniensis Regali Societati CCL annos 
gloriose exactos gratulatur, sperans fore ut futura eius tempora digna prae- 
teritis saeculis luce fulgeant.

Til Royal Society i London. Grundlaeggelsen af Royal Society for 
250 Aar siden var en Begivenhed, som ogsaa nu nied allerstorste Paaskonnelse 
maa mindes af enhver, som glaeder sig over den Hojde, hvortil Nutidens Natur- 
videnskab har haevet sig. Ved dets Stiftelse lagdes nemlig Grunden til store 
La;re : Bygninger, som siden den Tid ere voksede op, og som ere i Stand til at 
ba;re kommende Tiders rige Arbejder. Uforglemmelige i Videnskabens His- 
torie ere de hver paa sit Omraade fremragende Masnd, der samledes fiirst i en 
mere privat Kreds og dernaest i det af dem grundlagte Selskab for at fore- 
tage naturvidenskabelige Forscig i et Omfang og med en Planmsessighed, som 
ikke var kendt i tidligere Tider. Om den store Betydning af det Samarbejde 
mellem indenlandske og udenlandske Medlemmer, som Royal Society straks 
bragte tilveje, vidner den Brevveksling, som med det som Mellemled fortes 
mellem Newton og Leibniz, og som indeholder de vigtigste Dokumenter 
vedriirende Infinitesimah-egningens Tilbliven. Endelig var det under dette 
Selskabs Auspicier, at Newton nogle Aar senere, kraftig tilskyndet af dets 
ovrige Medlemmer, udgav sine Principia. Disse faa Trask vise den Hoved- 
andel, som Royal Society i sine forste Decennier havde i Grundlaeggelsen af

UUNivEBsiri; de Paris au President, au Conseil et aux mEiMbres de la 
Society Royale de Londres. — L'Universite de Paris est heureuse de se faire 
representor aux fetes donnees par la Societe Royale de Londres a Toccasion 
du deux cent cinquantieme anniversaire de sa fondation. Ce fut un jour 
memorable que celui ou le roi Charles II transforma en Societe Royale le club 
ou se reunissaient chaque semaine quelques curieux de la methode experimen- 
tale. Le programme de votre Charte etait de developper la nouvelle philo- 
sophic, comme on disait alors, c'est-a-dire la connaissance de la nature au 
moyen de Texperience. Votre Societe est toujours restee fidele a son premier 
but, et I'histoire de la Science montre avec quel eclat vous avez contribue au 
developpement de ce que vous appelez encore aujourd'hui la philosophic 
naturelle. On ne peut se reporter aux premiers temps de votre fondation 
sans evoquer le souvenir de celui qui fut pendant vingt-quatre ans votre 
president, et dont un de vos poetes a dit eloquemment que c'est un honneur 
pour le genre humain qu'un tel homme ait existe. Toute louange pitlit a 
cote du nom d'Isaac Newton. II n'est pas une branche des sciences physico- 
mathematiques et des sciences naturelles qui n'ait ete enrichie par les travaux 
des membres de votre Compagnie. John Dalton et Humphry Davy comptent 
parmi les fondateurs de la chimie moderne, et les decouvertes de Faraday et 
de Maxwell en electricite ont eu d'immenses consequences. Toute une philo- 
sophie se rattache au nom de Charles Darwin, dont les admirables et patientes 
observations ont mis en evidence d'importants facteurs de revolution des etres 
vivants. Dans le grand labeur jamais termine, par lequel sY'difie peu a peu la 
Science, chaque nation apporte sa mentalite particuliere. Vos savants restent 
toujours soucieux des details et des applications. Quel liel exemple a donne 
un grand physicien, comme Lord Kelvin, dont Tesprit puissant, capable des 
speculations les plus elevees sur la thermodynamique et la theorie des atomes- 


tourbillons, s'attachait en meme temps aux questions pratiques de la naviga- 
tion et de la telegraphic transatlantique ! II fut aussi des votres, Tillustre 
Lord Lister qui, en s'inspirant des doctrines pastoriennes, a cr^^ une m^thode 
de pansement bouleversant la chirurgie, et s'est ainsi place parmi les bien- 
faiteurs de Thumanite. La Science est dans une perpetuelle Evolution. Les 
faits et les principes qui paraissent les mieux etablis restent toujours sujets k 
revision. Mais, pour les reviser, il faut parfois une singuliere audace. EUe 
ne vous a pas manque. Pres d'ici, des gaz nouveaux, Ttu-gon et ses conge- 
neres, ont ete extraits de Tair atmospherique tant de fois analyst par les plus 
illustres chimistes. Cest dans un laboratoire anglais que fut repris recem- 
ment Tantique probleme de la transmutation des elements et que la trans- 
formation du radium en helium a ete etablie ; ce souvenir, ou sont associees la 
science anglaise et la science fran^aise, est particulierement cher k I'Universite 
de Paris. La part aussi est considerable qui revient aux savants de votre 
pays dans les vues nouvelles sur les theories electroniques de la matiere. 
Depuis deux cent cinquante ans, I'influence de la Societe Royale n'a cesse de 
grandir. Ses Proceedings et ses Transactions comptent parmi les journaux 
scientifiques les plus renommes et vont porter au loin le temoignage de votre 
activite. Quelle gratitude tous les savants ne doivent-ils pas a la Societe 
Royale pour son Catalogue of Seientijic Papers pendant le xix° siecle, 
entreprise immense, devenue internationale pour le siecle actuel, mais dont 
vous avez conserve la haute direction. Cest encore a votre initiative qu'est 
due la creation de I'Association internationale des Academies ; grace a vous, 
le projet, digne du chancelier Bacon, d'une Academie Universelle ouverte a 
toutes les nations est devenu une realite. Vous vous etes toujours preoccupes 
du role social que doivent jouer les Societes savantes. II n'est pas en Angle- 
terre une gi-ande entreprise, ayant un caractere scientifique, sur laquelle vous 
n'ayez ete consultes, ou dont vous n'ayez suggere la creation. Qu'il nous 
suffise de rappeler, pour des temps recents, le Laboratoire national de Phy- 
sique, du a Tinitiative de votre Conseil, et qui reste place sous son controle 
direct. Un passe si brillant repond de Tavenir de la Societe Royale. L'Uni- 
versite de Paris lui apporte cordialement ses felicitations pour tant d'ceuvres 
accomplies. Puissent toujours ses membres, rassembles pour Tavancement de 
la connaissance de la nature, suivant les termes de votre Charte deux fois et 
demie seculaire, continuer a travailler pour le progres des sciences et la gloire 
de TAngleterre.

Messieurs et chees Confreres, — Parmi les voeux que vous recevez de tous 
cotes, a Toccasion de la celebration de votre deux cent cinquantieme Anniver- 
saire, vous distinguerez, nous en sommes assures, ceux que I'AcADiiMiE des 
Sciences de Paris nous a charges de vous presenter en son nom. Vous 
connaissez de longue date les sentiments qui nous animent, Taffection que 
nous vous portons, I'admiration profonde que nous eprouvons pour vos 
travaux. Ces sentiments remontent a nos premieres origines. Notre Aca- 
demic et votre iUustre Societe ont eu des destinees a peu pres pareilles. L'une 
et I'autre ont ete etablies par les amis de la science, longtemps avant d'etre 
reconnues par le gouvernement de leur pays. Des le debut du xvii" siecle, 
nos savants de Paris avaient pris Thabitude de se reunir periodiquement, pour 
se proposer des problemes de mathematiques, pour faire des experiences, pour 
discuter les grandes questions scientifiques que susciterent les decouvertes 
de Kepler et de Galilee. Vers la meme epoque, vos philosophes, vos savants, 
dont plusieurs vinrent nous rendre visite, se reunissaient a Londres et a Oxford 
pour s'occuper,comme les notres, d'experiences et de recherches scientifiques. 
Lorsque ces assemblees qui se tenaient dans Tun et I'autre pays commencerent 
a y etre connues, elles ne tarderent pas a. recevoir Tinvestiture officielle. 
Charles II vous donnait votre premiere Charte en 1662. Quatre ans apres, 
en 1666, notre Academic recevait la sienne des mains de Louis XIV et de 
Colbert, ' ce ministre porte de lui-meme aux grands desseins ', en meme temps 
qu'etait decidee la creation de I'Observatoire de Paris. Nos commencements 
se ressemblent a plusieurs egards. Par exemple, dans cette premiere partie 
de leur carriere, nos Academies ont, I'une et I'autre, compte parmi leurs 
membres d'eminents medecins. II est vrai que les travaux de Newton n'ont 
pas tarde a illuminer vos debuts d'un eclat incomparable; notre Academic 
pent revendiquer du moins I'honneur d'avoir poursuivi et complete I'oeuvre 
de ce grand homme. D'Alembert, Clairaut, Laplace, Lagrange figureront 
dignement a cote des successeurs que vous avez donnes a Newton dans 
I'achevement de la plus glorieuse conquete qu'ait jamais faite I'esprit huniain. 
Cette union feconde de nos recherches s'est maintenue jusqu'a nos jours. 
Lorsque, vers la fin du xviii" siecle, Lavoisier a jete les bases de la Chimie 
modeme, ses travaux ont etc etroitement meles a ceux de Priestley et de 
Cavendish. Au siecle qui vient de finir, et pour ne parler que de ceux qui ne 
sont plus, la posterite reunira dans une admiration commune les noms de 
quelques-uns de nos confreres, et ceux a jamais iUustres d'Herschel, de 
Dalton, de Faraday, de Darwin, de Lord Kelvin, de Sylvester, de Cayley, 


d" Adams, de Maxwell, d'Huggins, de Lord Lister. Quelquc incomplete 
qu'elle puisse etre, cette enumeration montre bien que, tout en conservant 
Tempreinte de Newton, tout en vous attachant a cultiver cette science 
maitresse a. laquelle il a donno le beau nom de philosophie naturelle, vous 
n'avez neglige aucune branche du savoir' humain. La methode qui vous 
a guides pent etre aisement definie en quelques mots : Nullius in verba, telle 
a ete la devise que la Societe royale a toujours appliquee dans les travaux que, 
depuis sa fondation, Elle n'a cesse d'accomplir pour le developpement et 
raccroissement des sciences de la Nature. En repandaut ainsi, en faisant 
connaitre par vos propres recherches et par les directions que vous donnez, 
cette methode scientifique que le Chancelier Bacon avait preconisee avec tant 
de force et d'autorite, que Newton avait illustree dans ses Principta et dans 
son Optlque, vous avez rempli avec eclat la partie essentielle de la tache qui, 
de tout temps, a ete devolue aux Societes Savantes ; mais votre action s'est 
etendue plus loin encore et vous nous avez donne, sur d'autres points, des 
exemples que tous doivent s'efForcer d'imiter. Rattaches k votre gouveniement 
par des liens quelque peu laches, qui vous assurent une independance a peu 
pres complete, vous avez tenu neanmoins a lui rendre tous les services qu'un 
grand pays peut attendre d'une Societe Savante. Vous lui pretez votre 
concours pour la distribution des subventions aux recherches scientifiques, 
pour la direction de I'Observatoire de Greenwich, du Laboratoire national 
de physique, jjour Tetude des maladies tropicales qui se rencontrent dans 
votre Empire, le plus vaste que le monde ait jamais connu ; vous provoquez, 
vous sollicitez sa cooperation pour les expeditions maritimes et scientifiques, 
pour les decouvertes geographiques, pour Tetude des tremblements de terre, 
de I'Ocean dans ses profondeurs, et pour bien d'autres objets que nous 
renon^ons a enumerer. Tant de travaux, tant de preoccupations sont loin 
d'epuiser votre activitc ; et Ton vous a toujours trouves animes d'un esprit 
large et vraiment liberal, prets^a susciter et k faire vivre ces associations 
internationales qui sont appelees a prendre une place de plus en plus bienfai- 
sante dans le developpement et dans la vie de Phumanite. Naguere, vous 
cooperiez avec nous a la creation de I'Association internationale des Academies ; 
vous avez voulu diriger vous-memes une des entreprises les plus difficiles qui 
aient jamais ete tentees : nous voulons parler du Catalogue international de 
litteratwr scientifique, qui a ete deja, et qui sera plus encore dans Tavenir, 
si utile, si necessaire aux chei'cheurs de tous les pays. Les services que vous 
avez ainsi rendus a votre pays, a la science et a I'humanite meritent le respect 
et I'admiration que vous apportent aujoui'd'hui tant de voix autorisees, 
auxquelles nous sommes heureux de joindre les notres. Puissiez-vous prosperer 
longtemps encore pour servir d'exemple a nos Societes Savantes, pour offrir 
a votre pays et aux savants de toutes les nations une moisson de plus en plus 
ample de ces decouvertes qui sont marquees au coin de toutes les qualites, 
du genie de votre race ! tel est le voeu bien cordial et bien sincere que vous 


presentent en ce jour vos confreres, permettez-nous de dire vos amis, de 
I'Academie des Sciences de Paris.

adresse a la Societe Royale de Londres a Toccasion du 250® anniversaire de 
sa fondation son salut confratemel et son voeu cordial de prosperite. 
Londres et Bordeaux sont unis, depuis pres de deux mille ans, par des liens 
qu'ont noues des interets economiques communs, qu'ont resserres des affinites 
naturelles "et des sympathies inalterables. Des I'epoque romaine Bordeaux 
fut le point de depart de la voie qui mene de France en Grande-Bretagne et 
dont Londres est le point d'arrivee. Au Moyen Age, pendant trois siecles, 
les deux cites eurent des destinees semblables. Le meme roi d'Angleterre, due 
d'Aquitaine, qui signa la Grande Charte, donna aux Bordelais ces franchises 
communales dont ils gardent pieusement la tradition. La prosperite com- 
merciale, nee des echanges entre Londres et Bordeaux, a pour jamais garanti 
a notre ville son prestige de metropole du Sud-Ouest de la France. Cet 


amour des liberies munieipales et cette solidarite economique sont les deux 
traits caracteristiques de Phistoire de Bordeaux. Au xviii^ siecle un nouveau 
lien, d'une autre nature, fut none. Cinquante ans apres Londres, Bordeaux 
voulut avoir sa Societe royale, vouee, elle aussi, a Tetude et au progres des 
sciences de la nature. Des relations tres nobles, dont nos registres conservent 
la trace, s'etablirent entre la jeune Academie bordelaise et son cminente sceur 
ainee. L'honneur en revient au membre le plus illustre de notre Compagnie, 
a rimmortel penseur qui revela a la France la beaute de la constitution 
anglaise, au grand Montesquieu. A la veille de celebrer le deuxieme 
centenaire de sa fondation, TAcadeniie de Bordeaux est fiere de rappeler 
ces souvenirs. Puissent-ils resserrer, d'une fa^on plus etroite encore, les liens 
seculaires de nos deux cites, afFermir la cordiale entente de nos deux nations, 
gage de la paix du monde !

UNivERsrr6 DE Nancy. — Monsieur le President, — Un navire, a pleines 
voiles, franchissant la barriere des deux colonnes d'Hercule, dont I'antiquite 
avait dit qu'on n'irait pas plus loin ; au-dessous, cette inscription, empruntee 
a la Bible, Multi pertransibunt et augebitur Scientia, ' Beaucoup passeront, et 


le doniaine de la Science sera augniente'': telle est Tiniage et telle est la devise 
graveus au-devant dii Novum Organum de Francis Bacon. Prophetiqiies 
paroles, qui devaient trouver leur pleine realisation dans ['(jeiivre acconiplie 
par cette fille posthiime de son genie, la Societe Royale de Londres. Depuis 
deux siecles et denii, en eff'et, conibien de savants ont passe, qui, apres avoir 
explore toutes les parties du vaste monde scientifique, ont rapporte de leurs 
voyages, comine un eloquent livre de bord, ces deux cent onze volumes de 
vos Philosophical Transactiom ! Et quelle gloire pour eux d'avoir, sous les 
plis du pavilion britannique, conibattu le bon combat pour cet imperialisme 
de la Science, le plus grand et le plus beau de tons, le seul qui n'enregistre 
que des victoires, et dont beneficient tons les peuples ! Au dix-septieme 
siecle deja, un de nos esprits les plus curieux, qui sous un air frivole cachait 
le gout des choses serieuses, un Fran^'ais enfin, en etait emerveille, et s'inter- 
rompait dans une de ses Fables pour jeter cette reflexion : 

. . . Les Anglais pensent profondement. 
Creusant dans les sujets, et forts d'experiences, 
lis etendent partout I'enipire des sciences. 

Cet hoiiimage que vous rendait ingenument notre La Fontaine, toute la 
France savante vous Tapporte aujourd'hui : non seulement Paris, la capitale, 
mais aussi les diverses regions fran^'aises, et la notre en particulier: je veux 
dire la Lorraine. C'est la France de TEst, sensible plus que toute autre a la 
gloire scientifique, parce que, plus que toute autre, elle a appris k la connaitre 
en de glorieux fils nes de son sol : au siecle dernier, les matliematiciens Ponce- 
let et Hermite, I'un de Metz et I'autre du Pays messin, tons deux Lorrains, de 
cette Lorraine arrachee depuis lors a notre Patrie ; avant eux, Gergonne, 
connu par ses Annales, et Liouville, par son Journal; apres eux, le plus haut 
representant actuel des niatheniatiques parnii nous, un fils de Nancy meme, 
Henri Poincare. C'est un grand honneur pour notre jeime Universite de 
Nancy, de nieler sa voix a ce magpifique concert d'eloges qui retentissent de 
partout a la gloire de la Societe Royale de Londres. Par le norabre et la 
valeur de vos travaux, par I'illustration de vos savants, quen Angleterre la 
faveur publique aussi bien que le pouvoir reconipensent a I'envi, puissiez-vous 
toujours, comnie vous avez fait jusqu'ici, poursuivre au cours des ages votre 
fucond labeur, pro Dignitate et Augmentis Scientiartim, disait encore Bacon

Der Royal Society of London entbietet zur Feier ihres 250jahrigen 
Bestehens die Koniglich Preussische Akademie der Wissenschaften zu 
Berlin herzlichen Gluckwunsch und schwesterlichen Gruss. — Wenn auch 
einige andere wissenschaftliche Gesellschaften auf ein ebenso ehrwiirdiges 
Alter zuriJckblicken kiinnen, so darf sich doch die Royal Society riihmen, in 
dem Vierteljahrtausend ihi-es Bestehens auf dem von ihr gepflegten Gebiet 
der Naturwissenschaften mehr geleistet und auf die Entwickelung dieser 
Wissenszweige einen griisseren Einfluss ausgeiibt zu haben als irgendeine der 
gelehrten Korporationen aller Kulturvolker. Die Jubilarin ist nicht, wie 
viele ihrer Schwestern, aus kleinen Anfiingen zu ihrer heutigen Griisse und 
Bedeutung hervorgewachsen. Vollendet, wie Minerva dem Haupte Jupiters 
entstieg, tritt sie uns gleich nach ihrer Begriindung als eine stolze Genossen- 



schaft von Forschern ersten Ranges entgegen. In der Liste der Mitglieder, 
welche die Begeisterung fur die Wissenschaft und die Freude an der neuen 
Experimentierkunst im Jahre 1662 zu gemeinsamer Arbeit in den Raumen 
des Gresham College vereinigte, lesen wir mit Ehrfurcht die Namen von 
Robert Hooke, Robert Boyle und anderen, deren Entdeckungen heute die 
Grundlage weitverzweigter Wissensgebiete bilden. Aber der Glanz dieser 
Namen wird uberstrahlt von der leuchtenden Ruhmessonne Isaak Newtons, 
des griissten Physikers aller Zeiten und griissten Denkers auf dem Gebiet der 
Astronomie, wie ihn Helmholtz genannt hat. Mehr als die Begriinder selbst 
hat dieser gottbegnadete Meister, der wenige Jahre spiiter der Gesellschaft 
als Mitglied beitrat und wahrend eines Zeitraums von 24 Jahren ihr Prasi- 
dent war, der Royal Society den Stempel seiner Persiinlichkeit aufgepriigt. 
Es darf der Jubilarin das hohe Lob gespendet werden, dass sie stets von dem 
Geiste der grossen Manner beseelt war, die an ihrer Wiege gestanden haben 
und zu denen sich im Laufe der Jahrhunderte eine unabsehbare Reihe 
hervorragender Forscher auf alien Gebieten der Naturwissenschaften hinzuge- 
sellt hat. Frei in ihren Institutionen, ist sie durch alle Zeiten eine Pflegstatte 
der reinen, von Vorurteilen unbeirrten Forschung geblieben, eine fiir geistige 
Freiheit kiimpfende Genossenschaft, die ihre hohe Devise : ' Nullius in verba ' 
mit berechtigtem Stolze fiihrt. Moge sie in diesen edeln Traditionen fort- 
leben, moge es ihr vergonnt sein, auch in kiinftigen Zeiten eine so grosse Zahl 
hervorragender Manner und fiihrender Geister in ihrer Mitte zu vereinigen, 
und miige sie, den alten Ruhmesblattern stets neue hinzufiigend, auch ferner- 
hin die Wissenschaft mit neuer und immer reicherer Erkenntnis beschenken, 
zur Ehre ihres grossen Vaterlandes und zum Segen der ganzen Menschheit !

doctorum studio renovabantur atque ut ille apud Britannos, ita in Academiis 
Linceorum et Experimenti nostrates, Galileius eiusque discipuli, rerum 
natura qua ratione esset pervestiganda docebant, exemplo praemonstrabant, 
ab incunabulis suis usque ad hoc tempus in optimis artibus colendis promo- 
vendisque nunquam viam ceteris munire destitit ; quidquid autem eius 
auspiciis aut inventum aut investigatum est, id omnibus est hominibus 
patefactum celeberrimis editis actis'quibus nomen est Philosophical Trans- 
actions, quo exemplo usi sunt ceteri ad sua quoque inventa in lucem pro- 
ferenda. Magnum Newtonii nomen est cum Societate Regali Londinensi 
tam arte coniunctum, ut nemo possit de illius optimis inventis cogitare quin 
statim in Societatis memoriam redeat, cui ille usque ad extremum vitae 
diem praefuerit. Universitas Studiorum Romana vota pro Societate Regali 
Londinensi nuncupat precaturque ut prospera semper utatur fortuna atque 
summa ut nunc in perpetuum floreat gloria. Delegatus est qui personam

L'Institut oc^anographique fonde par le Prince de Monaco s'associe aux 
temoignages de respect que bien des corps scientifiques adressent aujourd'hui 
a leur doyenne en songeant avec reconnaissance aux efforts qu'elle fit avant 
tout autre pour agrandir le domaine de I'esprit. Les savants groupes autour 
du Prince apportent leurs felicitations pour ce 250"° anniversaire avec un 
empressement d'autant plus cordial que les savants anglais sont les premiers 
qui aient compris Timportance du role devolu a TOceanographie dans le 
progres des connaissances humaines. Cette circonstance est favorable pour 
reconnaitre la haute influence que la Societe Royale de Londres a su exercer 
sur le developpement scientifique de TAngleterre en faisant naitre parmi les 
esprits cultives la puissance de Tinitiative. C'est ainsi que les grandes 
exptjditions scientifiques con9ues par les savants de TAngleterre ont ^te presque 
toujours rendues effectives par le concours des particuliers. Souvent TEtat 
a joint sa contribution en homnies et en nature aux grandes entreprises telles 
que la croisiere du Challenger ; puisse-t-il intervenir plus largement encore 
pour la solution des problemes scientifiques dont la recherche etablit mieux 
que toute autre manifestation d'energie le prestige moral d'une nation. Un 
Etat qui favorise la culture de I'esprit sans entraver le libre essor des opinions 
fait honneur au pays dont il est une emanation. D'ailleurs la Grande 
Bretagne qui a montre comment un peuple edifie sa puissance, son prestige et 
sa prosperite en respectant ce qu'il y a de noble et d'emouvant dans ses 
traditions, la Grande Bretagne possede dej4, avec la longue existence de votre 
Societe Royale, la tradition scientifique. Aussi une ehte intellectuelle vient 


aujourd'hui saluer le genie du Peuple Britaiinique dans una de ses plus belles 
fructifications. Les hommes de science ne revendiquent pas un privilege 
exclusif dans revolution de la mentalite humaine : de grands cerveaux ont 
cultive les elements de celle-ci lorsque la science n'existait pas encore, niais 
quand, deja, la recherche de la verite en toute chose lui preparait les voies. 
Cest pourquoi nous voulons glorifier la memoire des homines qui se sont 
illustres dans les diverses branches de Tactivite intellectuelle, qui ont repandu 
sur la Grande Bretagne les premiers bienfaits de la civilisation modeme, 
et dont la renommee se confond avec celle de la Societe Royale,

Royal Acabemy of Sciences, Amsterdam 

The Royal Academy of Sciences of Amsterdam offers its best con- 
gratulations to the Royal Society of London on the occasion of the cele- 
bration of its two hundred and fiftieth anniversary. In these two hundred 
and fifty years Science has reached a high degree of development, to which 
the Royal Society, as one of the earliest scientific institutions, has powerfully 
contributed. The Royal Academy of Sciences remembers with pleasure the 
feelings of friendship which have always existed between the Royal Society 
and Dutch scholars throughout the period of its existence. For ever memo- 
rable, not only to the Academy, but also to the whole of the Dutch nation, 
will be the encouragement which the Royal Society shortly after its founda- 
tion gave to Leeuwenhoek by appointing him a Fellow of the Society in 1679, 
a distinction highly valued by him, and which has undoubtedly been pro- 
motive both to the production and to the spread of his inventions, which he 
communicated in a correspondence with the Royal Society extending over 
forty-four years. Further the Academy recalls on this occasion with great 
acknowledgement, how Christian Huygens, the contemporary and corre- 
spondent of Newton, Flamsteed, Boyle, Locke, with which famous men he was 
personally acquainted, was one of the first foreign members of the Royal 
Society. And how on Boerhaave, also a Fellow of the Royal Society, the 
special honour was conferred that Cromwell Mortimer, then Secretai-y of the 
Royal Society, dedicated the thirty-ninth volume of the Philosophkal 
Transactions to this scholar in 1735. The Royal Academy of Sciences 
wishes the Royal Society many years of great prosperity, and expresses the 
hope that the mutual feelings of friendship, which have been entertained for 
two and a half centuries, may continue to exist in the future.

Dutch Society of Sciences, Haarlem 

The President and Council of the Dutch Society of Sciences offer their 
most sincere congratulations to the Royal Society on the occasion of its 
250th anniversary. Few Societies can look back on an uninterrupted existence 
of two and a half centuries, less on a continuous activity during so long 
a time and none on a higher class of scientific work than that published 
by the Royal Society. The President and Council of the Dutch Society of 
Sciences can therefore frame no better wish, than that the Royal Society may 
for many more centuries continue to promote knowledge and consequently 
human happiness in the same admirable way as heretofore. For the Presi- 
dent and Council of the Dutch Society of Sciences,

Royal University of Noravay, Christiania 

The Royal University of Norway to the Royal Society of London, 
Greeting. A quarter of a millennium has elapsed since the foundation of the 
Royal Society. Since the days of Boyle and Newton, the Royal Society has 
enrolled on its list of members the names of almost all the eminent scientists 
of Great Britain, and among these are recorded the illustrious names of 
founders of all branches of modern science. Always alive to the vast 
importance of science to the various spheres of mental life throughout the 
world, the Royal Society has, in all likelihood, contributed more towards 
the development and advancement of mankind than any other scientific 
association. As a natural consequence of this leading position among 



scientific institutions, the Royal Society has suggested the foundation of 
'the International Association of Academies', and has thus enhanced the 
prospect of establishing solidarity within the domains of scientific research 
throughout the universe. The innumerable momentous scientific results and 
the fundamental ideas this illustrious Society has given to the world merit 
the admiration and gratitude of all, especially of the scientific institutions of 
all countries. The Royal University of Norway therefore begs to express its 
gratitude for the weighty contributions your Society has yielded to the 
common work of culture, and tenders heartiest greetings and congratulations 
on the occasion of your 250th anniversary, coupled with best wishes for ever 
increasing prosperity.

To THE Royal Society. — On the occasion of the 250th anniversary of the 
Royal Society the Societas Scientiarum Fennica begs to present its sincere 
congratulations and to express its admiration and profound esteem. The 
Royal Society was already one of the chief centres of science before the time 
when the great author of Principia Mathematica became its president. Vast 
indeed has been the growth of the knowledge which it has witnessed and, 
through its own work, promoted during these two and a half centuries, from 
a time when the Mosaic cosmogony held universal sway and the alchemist 


was still striving after the philosopher's stone down to the days of Darwinism, 
radioactivity, and the application of science in all departments of human life. 
It has seen the birth of many academies, from the antipodes almost to the 
polar circle, but ever maintains in their midst its position of leadership. Its 
publications, beginning with the Proceedings and Philosophkal Trajuactions, 
and ending with the new International Catalogue of Scientific Literature, still 
carry out to the full its object : ' to improve Natural Knowledge.' To the 
many brilliant names which have illuminated its annals, and still do so, new 
ones will be added in the future ; and each time a fresh star flashes into being 
in this bright constellation — one of the greatest in the firmament of science — 
that admiration will steadily increase which the scientists of the whole world 
feel towards your Society. We have the firm conviction that it will, during 
a limitless future, continue its truly royal work. On behalf of the Societas 

Scientiarum Fennica.

se sont etablis depuis I'epoque de la Reformation entre les hommes de science 
de la Grande Bretagne et de la Cite genevoise. Dans une adresse remarquable, 
precieuse entre beaucoup, envoyee en 1909 a I'Universite de Geneve, a Toccasion 
du jubile commemoratif de sa fondation, votre President rappelait les noms 
de nos maitres qui ont figure sur la liste d'honneur de la Royal Society. Les 
solennitcs du 250' anniversaire de la fondation de votre Societe nous rappellent 
deux noms de savants anglais qui nous sont chers : celui de Robert Boyle, 
dont les grandes decouvertes sont precisement de Tepoque ou votre illustre 
Compagnie s'est constituee, et qui,_peu de temps auparavant, passait comma 
jeune etudiant deux annees a Geneve ; celui de Sir Humphry Davy qui, apres 
avoir sejournc plus d'une fois dans notre ville, y decedait en 1829 et auquel 
notre petite Republique, toujours jalouse des prerogatives de la haute culture, 
fit des funerailles officielles. Ce souvenir s'est perpe'tue chez nous sous la 
forme d'un prix universitaire qui porte le nom de Davy : recemment encore, la 
vie de ce savant illustre etait donnee en exemple a nos etudiants dans une de nos 
fetes academiques. II nous a paru utile d'evoquer ainsi le passe pour mieux 
exprimer le caractere des liens qui unissent notre Universite a votre savante 
Confr^rie. Que la Royal Society continue a briller au premier rang des

TiONS ET SES HOMMAGES. — Cet anniversaire attire les regards du monde savant 
tout entier vers votre Societe, si venerable par son glorieux passe, si jeune par 
son inlassable activite. Vos fondateurs ont ete bien inspires, et doues en 
quelque sorte d'une vue prophetique, quand ils assignerent comme but a votre 
Societe Texploration experimentale de la Nature. Les deux cent cinquante 
ans ecoules depuis lors furent d'une fecondite incomparablement plus grande 
que les siecles qui les ont precedes. Des relations nouveUes ont ete decouvertes, 
la chaleur et la mecanique, Toptique et I'electricite se sont reunies dans des 
sciences plus larges et le philosophe, de plus en plus, entre en possession d'une 
vue d'ensemble des phenomenes naturels. Mais plus apparentes encore sont 
les transformations operees dans les conditions de la vie materielle. Par una 
serie de brillantes decouvertes Thomme a decuple ses moyens d'action, sa 
richesse ; la duree de la vie elle-merae a ete prolongee. Dans cette oeuvre, 
Messieurs, votre part a ete grande. L'histoire de la Societe Royale est 
rhistoire d'une notable fraction de la pensee humaine. Vos annales sont 
pleines de noms glorieux, que nous ne pouvons tons enumerer. Quelques-uns, 
tres grands, sont dans toutes les memoires et appartiennent a tous : NewtoUj 
Faraday, Darwin, Maxwell, Joule, Kelvin. D'autres, presents parmi vous et 
tres grands aussi, continuent la lignee de ces illustres devanciers. La Suisse 
que rapproche de votre pays la parente des institutions et un egal amour de la 
liberte a, elle aussi, compris de bonne heure ce que pent la Science pour la 
culture des esprits et la grandeur des nations. Penetree des pensees qui 
animent votre Societe, elle doit a I'esprit experimental le developpement de 
son Industrie et son role initiateur dans les oeuvres d'education. Les fetes 


auxquelles vous nous avez convies proclament bien haut la vertu efficace d'une 
idee qui fut la votre et qui nous est chere. EUes prouvent au monde entier 
qu'une institution, pour prosperer, pour devenir non seulement grande par la 
Science, mais aussi puissante par son action et bienfaisante par son rayonne- 
ment, doit rester en communion intime avee la masse de rtiumanite qu'elle 
eclaire et qu'elle guide dans sa marche vers de lointaines destinces. La Suisse 
s'associe avec une emotion profonde a des fetes qui sont celles de la Science 
tout entiere et aux voeux que Thumanitc pensante forme pour la Societe Royale.

Address of Congratulation from the Imperial University of Tokyo to 
THE Royal Society of London. — {Translation.) The Imjierial University of 
Tokyo is much honoured in being invited by the Royal Society of London to 
participate in the celebration of the two hundred and fiftieth anniversary of 
its foundation, and is delighted to join with other Universities and Learned 
Societies in tendering most hearty congratulations on this memorable occasion. 
So marvellous has been the progress of Science during the last two and a half 
centuries, and so illustrious the history of the Royal Society, its foremost 
promoter, that we cannot, in this short address, refer in adequate terms to 
any of the individual work of its Fellows, however important that work may 
be. We can but gratefully recall the fact that the two fundamental laws of 
Nature — the law of universal attraction and the law of evolution — were both 
brought to light by the Fellows of the Royal Society, one of whom held the 
office of President for the long period of twenty-four years and is, probably, 
the greatest man of science the world has ever produced. We would rather 
signalize the profound influence which the Royal Society has had upon man's 
thought. By steadfastly pursuing the great and noble object with which it 
was founded, the Royal Society has not only enlarged the bounds of man's 
knowledge and increased his power and happiness to an extent almost beyond 
words, but has also, especially during the last half-century, broken down 
inherited prejudices and traditional opinions, established freer and more 
direct methods of reasoning, and altogether raised the standard and widened 
the sphere of man's thought. And, immense as are the material benefits 
which Science hsis conferred upon mankind, this greater intellectual freedom 


and this wider range of thought, which have chiefly followed from the work 
of the Royal Society, are certainly not of less price. Moreover, when we 
remember that the bringing in of this liberal mental attitude has been of 
immense service in remodelling the civilization of Japan within the last fifty 
years, we feel that no words can adequately express our deep sense of 
gratitude. If, on this occasion of world-wide significance, we are allowetl to 
refer to another matter, which still more directly concerns the Imperial 
University of Tokyo, we would gratefully record the valuable assistance 
rendered to us in past days by several, who have since become Fellows of the 
Royal Society, in fostering the spirit of scientific investigation in this country. 
We must not omit to express our grateful thanks also for the active part 
taken by the Royal Society in initiating and organizing the International 
Catalogue of Scientific Literature and the Internationeil Association of 
Academies. Such international organizations are not only of great impor- 
tance for the primary objects with which they have been established, but will 
also be a powerful means of promoting the brotherhood of mankind. In 
conclusion, the Imperial University of Tokyo tenders its most hearty good 
wishes for the prosperity of the Royal Society and hopes that in the future, as 
in the past, it may lead the world in 'The Promotion of Natural Knowledge'. 
On behalf of the Imperial University of Tokyo.

To THE Royal Society of London fob Improving Natural Knowledge, 
Greetings from the Imperial University of Kyoto. — The progress of the 
world is due to the development of "science and art. Especially has the advance- 
ment of the physical sciences been a predominant factor in producing the 
increased welfare of humanity. The philosophy, the literature, and the Arts 
of every age are the flowers of its endeavour ; but it is always the advance- 
ment of the physical sciences that increases our knowledge of nature and 
points the way to its exploitation, thus substantially promoting the well- 
being of mankind. Great Britain has produced many scholars remarkable in 
different spheres of human learning ; but those who are distinguished in the 
physical sciences are especially numerous. This is due in part to the 
innate character of the English people who particularly love positive and 
practical knowledge ; yet more especially is it due to those varied means for 
promoting and encouraging scientific research in which Great Britain abounds. 
The Royal Society of London for Improving Natural Knowledge was estab- 
lished with the approval of Charles II, and incorporated in sixteen hundred 


and sixty-two. It is the oldest scientific association in Great Britain, and 
one of the oldest in the world. Among its fellows are included those of the 
greatest scientific eminence in Great Britain ; and by their indefatigable 
activity in the realm of natural science and by their keen counsel, the Society 
has wonderfully fulfilled its purpose. The institution, by the Society, of the 
annual grants for the promotion of scientific research, and of awards of 
various medals to those making important discoveries, has been of great 
service to the progress of knowledge in physical sciences. The publications of 
the Society are among the most useful agencies for encouraging and dis- 
seminating scientific information throughout the world ; and by them Japan 
has been greatly benefited. The Imperial University of Kyoto appreciates 
highly the Society's cordial invitation to participate in the celebration of its* 
two hundred and fiftieth anniversary, and herewith commissions her repre- 
sentative to attend the ceremony, paying honour to the Society's glorious past 
and praying for its still more glorious future.

University of Wisconsin 

To THE Royal Society of London. — The University of Wisconsin sends 
to the Royal Society of London its congratulations on the two hundred and 
fiftieth Anniversary of its foundation, a memorable event in the history of the 
oldest and most noted scientific society of the English-speaking people. Its 
long roll of members contains the names of many men who have initiated 
great movements in science, and includes others less distinguished by whose 
wisdom and labour science has become enriched. By the lives and work of 
these men the Royal Society has contributed in large measure to the great 
intellectual heritage of England, and through that nation to the enlightenment 
and freedom of the human race. The University of Wisconsin, while gratefully 
recognizing with all the world of learning this unique service, has the con- 
fident belief that the Royal Society during the centuries to come will continue 
its illustrious history.

for the Promotion of Natural Knowledge. — The Franklin Institute of thk 
State of Pennsylvania for the Promotion of the Mechanic Arts extends to 
you cordial greetings and sincere congratulations on the happy occasion of the 
two hundred and fiftieth Anniversary of the Incorporation of your Society. 
Few charters looking to the progress and welfare of peoples have resulted in 
greater benefits to civilization than that granted to the Royal Society by 
King Charles II, and no similar society can boast such a long and unbroken 


chain of illustriousmen whose labours have done so much to unravel the secrets 
of nature and subdue her forces to the uses of man. The Franklin Institute 
is glad to have this opportunity to acknowledge its deep indebtedness for the 
inspiration and incentive continuously derived since its founding from the 
Proceedings and Transactions of the Royal Society and from the many 
distinguished men who have represented the Society in America.

Royal Society of Tasmania, Hobart 

The President, Royal Sociexy of London. Sir, — The President, Council, 
and Members of the Royal Society of Tasmania desire, most cordially and 
sincerely, to offer to the Royal Society of London their heartiest congratu- 
lations on the two hundred and fiftieth Anniversary of its foundation. 
Honoured by the name of the parent Society, and working to promote its 
objects in Tasmania, we join with other kindred bodies in gratefully recalling 
the past of the Royal Society of London, rich in names of men who have 
profoundly influenced the progress of Science, and who for such service have 
gained world-wide renown. On this Anniversary not the least cause of pride 
in the great work of the Society must be the thought that its methods and 
ideals are animating the lives of men in parts of the world entirely unknown 
to its distinguished founders. We, at this time, also recall the fact that 


it was at the instance of the Royal Society of London that Captain James 
Cook was sent out by the Enghsh Admiralty on that voyage which led 
to such remarkable results in the history of these Southern Lands, results 
none the less famous in Science from the labours of Sir Joseph Banks, 
afterwards your President for over forty years. The Royal Society of 
London has ever been pre-eminent in promoting the highest ideals of 
knowledge and truth. It has helped in a unique degree to mould the 
intellectual life not only of Britain but also of Europe and the whole civilized 
world. While it is impossible to estimate the enormous influence that has 
radiated from it during the two and a half centuries of its existence, yet this 
aspect may be specially noted : there can be no national bond stronger than 
that of common scientific interest, and in carrying out its more definite 
objects the Royal Society of London has also been eminently assisting to 
draw closer the political and social bonds of the Empire. The Royal Society 
of Tasmania names as its delegate and representative to convey this greeting, 
Gregory Sprott, M.D., Member of the Council. Signed on behalf of the 
Council and Members of the Royal Society of Tasmania.

The President, Council, and Members of the Royal Society of Victoria, 
a humble but aspiring unit of the body of seekers after knowledge, send hearty 
greetings to the Royal Society of London, its great mother and prototype, on the 
completion of the 250th year of its valuable life. The faithful work of many 
devoted students of nature in the London Society has brought fresh light into 
countless dark places, and the stimulus given by them, rolling like a wave to the 
remotest comers of the British Empire, inspires distant workers in the fields 
of science with energy and hope to new endeavours. The Royal Society of 
Victoria gratefully acknowledges its debt to these noble men, and ventures to 
trust that the efforts of its own members to emulate the work of the parent 
Society may have added some vigour to the growth of the Tree of Knowledge, 
that by continuing so to do it may be for ever weaving fibres of kinship that 
shall assimilate its results ever more closely to those of its illustrious progenitor. 
By order of the Council :

to the Meetings celebrating the 250th anniversary of the

University of Bombay 

To THE President, Council, and Fellows of the Royal Society of 
London, on the occasion of the 250th Anniversary of the Constitution 
of the Society by Royal Warrant. — The UNivERsrrY of Bombay, in accepting 
the invitation of the President, Council, and Fellows of the Royal Society 
of London to send a delegate to the celebration of the two hundred and 
fiftieth Anniversary of its constitution by King Charles II, desires to convey 
through its representative. Dr. F. G. Selby, M.A. (Oxon.), LL.D. (Bom.), 
its cordial felicitation, and to express its sympathetic interest in the historical 
commemoration of one of the most important events in the history of 
scientific inquiry in any part of the world. In the University of Bombay, 
as in every other seat of learning and research, the influence of the Royal 
Society has been a stimulus to investigation and interpretation in many 
different fields, and it is with gratitude that the LTniversity desires to share 
in the celebration. The University of Bombay is specially anxious to be 
identified with the celebration because the Royal Society has during its 
history taken such a very large interest in the development of inquiry in the 


tropics and specially in India. Several of its leaders, and notably Sir Joseph 
Banks, President of the Royal Society in the latter part of the eighteenth 
century, and Sir Joseph Dalton Plooker, one of its most eminent members 
in the nineteenth century, spent much of their life and strength in investigation 
into tropical conditions, and were almost the first to draw attention to the 
important light which such inquiry would shed on general scientific questions. 
The interest in tropical and Indian questions has not flagged since that time, 
and the Society has again and again placed its experience at the disposal 
of the Government of India and private bodies in this country. At the 
present time it acts as the adviser of the Indian Government on matters 
connected with scientific inquiry in India, and also as an advisory body 
on the management of the Observatories in India. It has Committees which 
are studying tropical diseases which are among our worst scourges. And the 
Royal Society has always shown itself willing to assist with advice and counsel, 
any public body which appealed to it. The University of Bombay, therefore, 
joins in congratulating the Royal Society of London on the present occasion, 
on the noble part it has played in the advancement of knowledge in the past, 
and wishes for it a future even more glorious, in which it will appear that the 
present commemoration represents but the beginning of a new era of advance- 
ment and usefulness.

1. Those who daily improve the modern world by new discoveries, who 
spend their lives in search after truths about the material world, who plunging 
deep into the ocean of science collect gems, may those sober-minded scientists 
live for ever for the benefit of this world. 

2. Many learned men were bom, will be bom, and are being bom on this 
earth which was created long ago ; but indeed there are few who are really 
successful and who by diving into the ocean of science have found out hidden 

3. The Creator, hoary with age, created the universe with the earth and 
other elements ; but surely he concealed the forces of material objects. 
A new creator, more powerful than the first, being born discovered the long- 
hidden forces of material objects. 

4. In the store-house of the universe created by the aged sage Brahma 
many precious things were kept hidden ; but Newton breaking open the doors 
of superstition revealed a new method of discovery. 

5. May the bright glory of the Royal Society, founded by him, continue to 
shine through Royal patronage as long as the Sun and the Moon endure. It 



is time for us to celebrate the jubilee, now that it has completed its two 
hundred and fiftieth year of existence. 

6. Electricity, fire, water, and other elements that were ever known as 
inanimate things caught in the machines (of the Society) toil like ghosts 
discharging vapour (tears), and constantly propel steam-ships, etc. during the 
day and night : seeing this wonderful mechanical skill the Creator himself is 
now surprised. 

7. Within London lies the famous tank, called the Royal Society, in whose 
waters of science on white lotuses plays the Goddess of Learning in her 

■"^'*' splendour and where the Sun of knowledge never sets but always shines out of 

joy. To add to the beauty of that tank we send this fresh blooming lotus 
(Praphullachandra) of our own country. 

8. May the garland of this poem composed by Asutosh and presented by 
him with deep regard be accepted. If the savants living in the garden of 
science wear it as an ornament, then his labour will be requited,

\Translation from the original Sanskrit.^ 

The Asiatic Society of India offers her respects, regards, and reverence to 
the august Royal Society of august England, the importer of scientific know- 

Be it known : — 

How can one describe thy glory, O Society ? Full two centuries and a half 
have elapsed since thy foundation at the command of the Sovereign. Asia 


offers her tribute to Europe in the garb of this eulogy of thee. May the wise 
rejoice at the sight of this union of ours, so beneficial to the world. Vibhvana, 
Vfija and Rbhu, celebrated in the Rig Veda, these three together rejuvenated 
their old father and attained to heaven. Still higher and all unrivalled is the 
region that you have reached by rejuvenating the old world through Science 
and Art. 

Vayu, Varuna, Agni, the Asvins, Rudras and Vasus, worshipped by the 
Aryans of old, have been praised in beautiful hymns in the Vedas ; through 
thy constantly employing all of them in devoted service for the good of 
humanity, thy glory, moving among the regions of the air and the waters, 
extends over the earth. Having come to congratulate thee, O [Society] of 
glorious fame and unequalled majesty, I am satisfied with thy various virtues.

University of Leeds 

To THE President, Council, and Feij-ows ok the Royai, Society. — Thk 
University of Leeds begs respectfully to congratulate you on the Anniversary 
which you are about to celebrate. For two hundred and fifty yeai-s your 
Society has filled a unique place in our national life. No institution has 
ever been animated by a greater love of truth or by a deeper reverence for 
unfettered freedom of thought. The experimental methods followed by the 
Royal Society have proved themselves to be true methods of advance ; and 
to-day mankind is its debtor for the enlightenment and the welfare which 
attend v£ist additions to natural knowledge. The scientific achievements of 
your Society are universally acknowledged both at home and abroad. A point 
less generally observed is its indirect influence in all parts of the British 
realms. Happily inclusion in the Royal Society does not withdraw and 
isolate men who have found a career among the growing populations of our 
time. No thoughtful dweller in our own city can help feeling that Leeds 
would have lost greatly had Joseph Priestley never lived and worked here. 
In large industrial centres men like Priestley are the best of educators. 
They are true 'merchants of light', if we may borrow a phrase from that 
New Atlantis which foreshadows so closely, in some important respects, the 
purposes of your own foundation. And since Priestley's day there have never 
been wanting among the citizens of Leeds other members of your body who 
have not merely advanced natural science by special research but have spared 
no effbrt to encourage learning in all its many branches. Not the least 
active among the founders of our University have been Fellows of the Royal 
Society who have not allowed the claims of particular investigations to blind 
them to the wide range and essential unity of human knowledge.

British Academy, London 

The President, Council, and Fellows of the Roval Society of London. — 
We, the President, late Presidents, Council, and Fellows of the British 
Academy, desire to offer to the President, Council, and Fellows of the Royal 
Society our cordial congi-atulations on the completion of the two hundred and 
fiftieth year of its illustrious career. On this memorable occasion we approach 
you with feelings of special attachment and confidence, inasmuch as our 
Academy was, at a still recent date, founded with the co-operation and good- 
will of your august Society, and we take pride in the thought that we may 
almost regard our own Body as the offshoot of an historic Institution which 
has flourished through so long a period of the national life. The Royal 
Society had its beginnings in troublous times, when the proud legend 
inscribed on the Society's seal found in very deed a wide application ; but at 
no time has it been other than true to the high and arduous ends to which its 
labours have from the first been devoted, or ceased from the pursuit and 


service of Truth. One of the earliest of the Associations founded in any 
European country 'for promoting Natural Knowledge', it has extended its 
investigations, so as to comprehend all the Physical as well as Mathematical 
Sciences, and the roll of its Presidents, Secretaries, and of successive generations 
of its Fellows, as well as of its Metlallists, covers the entire range of modern 
scientific {)rogres8. The ' Invisible College ' of the years preceding the Grant 
of the Society's first Charter, which it commemorates to-day, has long since 
established its leading position among the chief agencies in the advancement of 
'Natural Knowledge' throughout the world. Nor can we forget that the list 
of its Officers and Fellows includes many names notable in the annals of British 
Letters, and in the history of those Studies which have of late found particular 
representation among the members of our own Body. Of the long and varied 
labours of the Royal Society a record of monumental completeness is presented 
in its Transactions, extending over very nearly the whole of the two hundred 
and fifty years of its strenuous existence. To the work thus unintermittently 
carried on by the Society has been added its faithful and fruitful administration 
of the important trusts committed to it by the Government of the Country, 
and through other Benefactions, as well as its wise distribution of the Annual 
Grants made to it, and its judicious award of Distinctions marking great 
achievements in original Scientific Investigation. All these high and onerous 
functions have been performed by the Royal Society in a spirit of self-devotion 
and with a fullness of success which entitle it to the grateful acknowledge- 
ments of a long series of generations, including the present of which we form 
part. With the sincere expression, on the present great occasion, of this 
widespresid and well-merited recognition, the British Academy, in a spirit of 
faithful and grateful homage, desires most cordially to associate itself

British Museum, London 

To THE President, Council, and Fellows of the Royal Society. — The 
Tbustees of the British Museum desire to offer to you their cordial con- 
gratulations on the occasion of the two hundred and fiftieth Anniversary of 
the foundation of your Society. Few institutions for the advancement of 
natural knowledge can claim an existence of equal length ; none can boas-t 
a longer list of services to humanity than that which stands to the credit of 



the Royal Society and its Pellows. A Corporation such as yours, which 
includes within its ranks all the most eminent representatives of every branch 
of natural iinowledge within the British Dominions, which commands the 
confidence of the nation and receives the support of the Government, can 
direct and co-ordinate effort, can encourage enterprise, can reward achievement, 
and thereby can promote the advance and welfare of scientific investigation 
with a power altogether outside the reach of individuals or of special societies. 
The RoyeJ Society is one of the glories of England and the Empire ; and all 
Englishmen are glad to join in celebrating this landmark in its long career of 
usefulness. The Trustees of the British Museum feel that they have a special 
claim to approach you on this occasion and to share in your rejoicings. The 
British Museum owes its origin to a munificent bequest from a Fellow and 
President of the Royal Society, Sir Hans Sloane ; and the Act of Incorpora- 
tion, by which it was founded in 1753, ordains that among the official 
Trustees of the Museum shall always be the President of the Royal Society 
for the time being. Thus, throughout its whole existence, the British 
Museum has had the advantage of the counsel, and has enjoyed the support, 
of every President of your Society ; and not least would the Trustees grate- 
fully acknowledge the assistance they have received from the distinguished 
man of science who now holds that high and enviable post. The interests of 
the British Museum are closely intertwined with the interests of science. The 
Museum, in its Library and its Natural History Departments, provides the 
materials for a vast amount of scientific research. Much of that research has 
been conducted by the officers of the Museum, past and present, many of whom 
have received the coveted honour of the Fellowship of your Society. It is, 
therefore, with the interest that is born of close association and common 
aspirations that the British Museum, in the person of its Trustees, rejoices in 
the glorious past of the Royal Society, and wishes it a long and not less 
glorious future. ,

Chemical Society, London 

The Chemical Societv to the President, Councii., and Fellows of the 
Royal Society, Greeting. — Amongst the many learned bodies represented 
here to-day there is certainly none which can wish to offer you more sincere 
and heartfelt congratulations than the Chemical Society. The Officers, 
Council, and Fellows of our Society desire to associate themselves with you 
in celebrating the two hundred and fiftieth Anniversary of the birth of 
a scientific corporation which in the distinction of its history is assuredly 


second to no similar body in the World. The great army of diligent and 
determined workers who are united by the solemn covenant to extend Man's 
knowledge of Nature look with reverence and gratitude on the Society which, 
during two and a half centuries, has kept alive in these Islands the sacred fire 
of Research, and has included within its Fellowship men whose names and 
achievements are amongst the most imperishable glories of the human race. 
We desire to take this opportunity of expressing, however imperfectly, our 
indebtedness to the Society of Boyle, of Cavendish, of Priestley, of Dalton, 
and of Davy, and we are proud to remember that these early masters of our 
Science, by the stimulus which their investigations gave to the growth of 
Chemical Knowledge, led to the origin of our Society by a natural process of 
gemmation from your body. It is, therefore, in the capacity of children, and 
as an act of filial piety, that we desire to offer to you, our parents, dutiful 
felicitations to-day. We would take this opportunity again of gladly and 
freely acknowledging before all men that whatever success our own Society 
may have achieved, whatever may be the dignity to which we have attained, 
and whatever service to Science and to Mankind we may have been privileged 
to perform, we largely owe to the inspiration which our founders drew from 
the magnificent traditions of the Royal Society. This quickening influence 
has been and, we trust, may long be maintained by a close association with 
you, by the community of Fellowship which exists between your Society and 
ours, and by the kindred ideals and aspirations which animate us both. 
Signed on behalf of the Chemical Society:

Geological Survey of Great Britain and Museum of 
Practical Geology, London 

Address of the Geological Survey of Great Britain and the Museum 
OF Practical Geology to the Royal Socieii' of London. — The Geological 
Survey of Great Britain and the Museum of Practical Geology desire to take 
their part in the congratulations which are being offered by the whole civilized 
world to the Royal Society of London on the attainment of its two hundred 
and fiftieth Anniversary. To the influence of the Society in carrying out its 
vocation of improving Natural Knowledge, the growth of the science of 
Geology was chiefly due for nearly a century and a half, and though now for 
upwards of a hundred years geologists have found other homes, they can never 
forget that the Royal Society is the parent of all scientific institutions in the 
British Dominions. The Geological Survey and Museum are proud to 
remember that all their Directors and many other members of their staff have 
been Fellows of the Royal Society, and more especially that a former Director 
General now occupies the Presidential Chair. Being well aware of the great 
work performed by the Society not only in original research in every branch 
of science but in advising the State on scientific matters, in administering 
funds for the furtherance of research, and in investigations leading to the 
improvement of man's position upon the earth, it is the fervent wish of these 
Institutions that the Royal Society of London may long continue its eminently 
distinguished and useful career.

Institute of_Chemistry, London 

The President, Council, and Fellows of the Institute of Chemistry of 
Great Britain and Ihel.\nd have great pleasure in offering to the President, 
Council, and Fellows of the Royal Society of London their sincere and hearty 
congratulations on the occasion of the two hundred and fiftieth Anniversary 
of the incorporation of the Society. The Institute of Chemistry desires to be 
associated with Academies, Learned Societies, and all Scientific Institutions in 
rejoicing that the Royal Society which justly takes precedence as the parent 
of all our Scientific Societies, has with such marked success upheld the world- 
wide prestige of Science generally, and that throughout the two and a half 
centuries of its existence the great objects of its founders have been faithfully 
maintained to the honour of this country, and to the everlasting benefit of the 
cause of civilization and humanity at large. In the domain of Chemistry, no 
less than in other branches of Science, the Royal Society has fostered the 


progress of Learning and Research. The Institute recalls with pride that 
from its foundation in 1877 its Register has home the names of no less than 
106 Fellows of the Royal Society, while at the present time 48 Fellows of the 
Institute enjoy that distinction. It is the earnest hope of the Institute that 
the Royal Society may continue its career with undiminished vigour and 
success and that the great traditions of its past history may be carried on by 
future generations of its Fellows.

Greeting. — The President and Council of the Institution of Electrical 
Engineers offer their congratulations to the Royal Society on the completion 
of the two hundred and fiftieth year of its existence. They are happy to 
recall how much the Royal Society has done since the days of Robert Boyle 
and Francis Hauksbee to promote the discovery of electrical phenomena and 
of the laws of electricity and magnetism. They will ever remember the 
additions to electrical knowledge due to Sir Isaac Newton, Stephen Gray, 
Benjamin Franklin, Joseph Priestley, Abraham Bennet, Sir Humphry Davy, 
Michael Faraday, John Frederick Daniell, Sir William Grove, Sir Francis 
Ronalds, James Prescott Joule, Sir Charles Wheatstone, John Tyndall, 
Latimer Clarke, David Edward Hughes, Lord Kelvin, James Clerk Maxwell, 
John Hopkinson, George Francis FitzGerald, William Edward Ayrton, and 
other Fellows of the Royal Society. They express the hope that the Royal 
Society may enjoy unbroken prosperity, and may continue to promote the 
progress of electrical science.

have been and are on the RoUs of both Societies, thereby constituting links 
between the two, but also that Sir Joseph Banks, who took a large part in the 
foundation of the Linnean Society, presided for forty-one years over the Royal 
Society, and that the great Swedish naturalist whose name is borne by the 
Linnean Society, was also a Foreign Member of the Royal Society.

Mathematical Society, London 

The London Mathematical Society, of whose duty it is part to elaborate 
the instrument without which all pursuit of Natural Knowledge must finally 
be futile, desires to offer humble congratulations on the attainment of her 
two hundred and fiftieth Anniversary to the Royal Society. That this 
Society may ever continue to be imbued with the reverent and enthusiastic 
desire to unravel the secrets of Nature which has characterized all her most 
distinguished Fellows, and may ever hold herself in readiness, untrammelled 
by any too intimate relations with other institutions, to take her rightful 
place in succeeding times of Renaissance, is the prayer of all the special 
societies who own her pre-eminence. On behalf of the London Mathematical 
Society :

To THE President, Council, and Fellows of the Royal Society. — The 
Mercers' Company of London desire to offer to you the President, Council, and 
Fellows of the Royal Society their sincere congratulations on the occurrence 
of the 250th Anniversary of the incorporation of your Society, whose history 
from its commencement has been an uninterrupted and glorious succession 
of conquests over Nature, conquests differing from other conquests in that they 


have been achieved, not by resistance to Nature, but by an ever increasing 
i<nowledge of and obedience to her laws. It is a further subject for 
congratulation that the true method by which these results have been 
achieved, the method of experiment and test, which was from the first laid 
down by your Society, was truly laid, and has since been universally aciinow- 
ledged. We acknowledge also the large share which, on a survey of your 
successes, must be attributed to the principle represented by the words which 
you have adopted as your motto and have so greatly fortified in action, the 
principle of the independence of the human intellect. We acitnowledge it with 
the more gratitude, since in supporting that principle you have conferred 
benefits on manicind not limited to the particular subjects which you have 
made more especially your own. We know, from the account which has been 
preserved, the ideas which actuated the founders of your Society, and it is very 
fitting that we of the present day, who can judge by the event the value of 
those ideas, should join with you in celebrating, and render our respectful 
homage to, the memory of those gifted men who formulated the principles and 
laid down the lines of your work, though they could only prophetically foresee 
the grandeur of the results to follow. May the Royal Society long continue 
its glorious career to the increase of true knowledge, the honour of our nation, 
and the welfare and happiness of the whole human race.

than those of the men who devoted themselves to the study of Physics. 
Newton firmly planted the Tree of Science, Young, Joule, Faraday, Maxwell, 
Stokes, and Lord Kelvin have spread its branches in many directions. May 
we, therefore, — a young Society specially devoted to the study of Physics — pay 
our warm tribute of regard and affection to the parent body whose members 
have laid the foundation on which we are trying to build ! May the record 
of the Royal Society be as glorious in the future as it has been in the past, 
and may she continue to possess the confidence and admiration of all who seek 
the advancement of Natural Knowledge ! On behalf of the Physical Society

To THE President, Council, and Fellows of the Royal Society of London. 
— We, the President, Council, and Fellows of the Royal Anthropological 
Institute of Great Britain and Ireland, desire to offer to you our hearty 
congratulations on the occasion of the completion of the two hundred and 
fiftieth year of your glorious history. Your Society has during that long 
period been the centre of scientific thought, the home of the most illustrious 
workers and discoverers in science, the representative throughout the world 


of British scientific research and the constant and trusted adviser and almoner 
of the Crown and the Government of the country in respect of all matters 
relating to the progress of Science. Our Institute has less than seventy years' 
record to look back upon, for the Ethnological Society of London, which forms 
part of it, was founded in 1843, and the Anthropological Society of London, 
which forms the other part of it, in 1863. The two Societies were combined in 
1871, and it is to one who conferred lustre on your Society, our then President, 
Thomas Henry Huxley, that that happy combination was due. We have 
owed much to other great men who, belonging to your body, have devoted 
themselves especially to the work of Anthropological Science, and have 
presided over our Institute. Among these are George Busk, Francis Galton, 
John Evans, John Beddoe, Augustus Franks, Augustus Pitt-Rivers, Daniel 
Cunningham, and others who are departed, as well as Lord Avebury, Alexan- 
der Macalister, Edward Burnet Tylor, and other distinguished members of 
your body who happily remain with us. It is to one of the ornaments of your 
Society — Charles Darwin — that the science of Anthropology owes its most 
powerful inspiration. The Origin of Species and the Descent of Man 
gave a new impulse and direction to the students of our science and formed 
for them a fresh starting-point for laborious and fruitful investigation. We 
have for many years felt the assured conviction that your body, as the 
acknowledged leaders of scientific thought, had the most complete sympathy 
with our work ; that you viewed the growing development of it with cordial 
satisfaction ; and that you had thus contributed much towards its successful 
prosecution. It is accordingly with a special feeling of gratification that we 
have deputed our President, Dr. A. P. Maudslay, to be our representative at 
the Celebration of your auspicious Anniversary and to present to you in our 
name this our Address of Congratulation.

We, the President, Vice-Presidents, and Council of the Royal Astronomical 
Society, desire to offer our most hearty congratulations to the Royal Society on 
the celebration of the 250th Annivei-sary of its foundation. We would testify 
to the unceasing efforts of the Royal Society to promote the advancement of 
Natural Knowledge, which have eminently contributed to the present remark- 
able development of the sciences and their application to technical and 
industrial arts. Particularly do we desire to acknowledge the beneficial 
influence of the Royal Society on the study of Astronomy evidenced by the 
large number of important memoirs on Astronomical Science found in its 
publications. We note with pride the long roll of distinguished Astronomers 


who have been Fellows of the Society ; and we are mindful that it was the 
extensive progress of Astronomy made in Great Britain under the encourage- 
ment of the Royal Society, which led to the formation of the Royal Astro- 
nomical Society. We are confident that the Royal Society will in the future, 
as in the past, continue to exercise the same fostering and effective influence 
upon the progress and development of all branches of Natural Knowledge.

Royal Geographical Society, London 

To THE President and Council of the Royal Society, from the President 
AND Council of the Royal Geographical Society. Gentlemen, — On behalf 
of the Council of the Royal Geographical Society, and as representing the 
Fellows, I desire to convey to you our warmest congratulations on the occasion 
of the celebration of the 250th Anniversary of the foundation of your Society. 
It would be superfluous for me to point out the claims which the Royal 
Society possesses upon the admiration and gratitude of all who have the 
interests of scientific progi-ess at heart. Through long years it was the only 
Institution in this country devoted to the encouragement and publication of the 
results of scientific research on purely disinterested lines, and without any hope 
of reward, except the satisfaction which follows the successful search for truth. 
The most illustrious names in all departments of Science have been connected 
with the Royal Society from its foundation. From the very first every serious 
research into any of the many aspects of the universe was welcomed by the 
Society, and the results were impartially considered. In time, and largely due 
to the action of the Royal Society, this work of scientific research became so 
multifarious that other Societies grew up alongside the parent Society, and 
co-operated in the common object of seeking after the truth, and attempting 
to interpret the phenomena of the universe. In past generations the subject 
with which the Society is directly concerned had its fair share of attention at 
the hands of the Royal Society, many of whose Fellows were specialists in 
Geography ; and the influence and example of the Royal Society have not been 
without their effect in inducing British geographers to apply scientific methods 
in an ever increasing degree to their own department of research. In 
pursuing its work the Royal Society has rendered eminent services to the 
Empire and to the world, and we confidently hope that in the future it will 
continue to occupy the commanding position in Science which it has attained 
in the past. On behalf of the Council and Fellows of the Royal Geographical 
Society, I am, Gentlemen, Your obedient servant,

To THE Royal Society, London. — We, the President and Council of the 
Royal Meteorological Society, desire to offer to the Royal Society our sincere 
congratulations on the occasion of the two hundred and fiftieth Anniversary of 
its foundation. We are deeply sensible of the pre-eminent position which the 
Royal Society has always held in the promotion of natural knowledge, and of 
the beneficial influence it has exerted upon the advancement of learning and 
also upon the scientific development of the technical and industrial arts, by its 
unceasing efforts. We recognize with especial satisfaction the support which 
the Royal Society has afforded to the science of Meteorology, as exemplified 
particularly in the labours of the Meteorological Committee. Many names 
eminent in meteorological science occur in the Roll of Fellowship of the 
Royal Society, and the published records of the Society contain numerous 
contributions of outstanding importance to our knowledge of the mechanics 
and physics of the atmosphere. In congratulating the Royal Society upon 
a long and brilliant record of past achievement we are assured that it will 
continue in the future to take an "Equally important part in the progress of 
all branches of science.

The Royal Society foe the Encoueagement of Aets, Manufactuees, 
AND CoMMEECE welcomes the opportunity which has been afforded to it of 
offering its warm congratulations and best wishes to the Royal Society on 
the 250th Anniversary of its foundation. Among the many services which 
the Royal Society has rendered to this country and to Science in general, 
one — not the least — has been that in proportion as the increase of knowledge 
has rendered necessary special and separate study of each branch of in- 
vestigation, the Society has been instrumental in the formation of fresh 
Associations for this purpose, while itself maintaining a general interest in 
the whole field of progress and discovery. The Society of Arts, in whose 
foundation a century and a half ago several Fellows of the Royal Society 
took a prominent part, has from its commencement looked 'to the Royal 
Society as the parent of such Associations in this country, no less than the 
model for similar combinations abroad, and congratulates itself on the close 
connexion between the two Societies, which has been maintained throughout 
its existence by the presence in its ranks of many distinguished Fellows of 
the Royal Society. The Council have had pleasure in deputing their Chairjiax 
to represent them among the distinguished crowd of Delegates who have 
come fi'om all countries of the world to take part in the celebration of this 
auspicious Anniversary, and they desire to express their earnest hope that 
the future may have in store for the first and greatest of English Scientific 
Societies achievements no less illustrious and beneficial to mankind than those 
which are recorded in its past history. Sealed with the Seal of the Royal

RoYAi, Society of Medicine, Londox 

The Royal Society of Medicink. — The President, Council, and Fellows 
of the Royal Society of Medicine very heartily congratulate the President, 
Council, and Fellows of the Royal Society on the completion of two hundred 
and fifty years spent in the execution of the very important duties with which 
it is entrusted. A Society which has for its object the improvement of the 
Art and Science of Medicine in all its branches, towards which improvement 
the advancement in knowledge in various other Sciences so largely contributes, 
cannot but take the warmest interest in the continued prosperity and use- 
fulness of the Royal Society, especially as there were among the original 
members of that Society several Fellows of the Royal College of Physicians 
of London, and as moreover several of its Presidents have been Fellows 
either of that College or of the Royal College of Surgeons of England. In 
former times when the power of Analysis had outrun the means of obtaining 
knowledge, natural Philosophy and Metaphysics and the analysis of Sense 
and the analysis of Thought were hopelessly confused by the attempt to 
solve them, not through an appeal to facts, but by the help of general 
theories respecting the nature of the Universe. In the philosophy of 
Antiquity the meaning of the word ' Science ' could scarcely be explained 
to students, except from the mathematical sciences, which alone offered the 
type of Universality and Certainty. Geometry was regarded as the pro- 
paedeutic to philosophy. Somewhat of this view perhaps lingered at the 
time when those who afterwards gave birth to the Royal Society had 'a 
designe of founding a Colledge for the promoting of Physico-Mathematicall- 
Experimentall Learning '. But the Royal Society — having arisen out of the 
'Invisible College' of which Boyle the disciple of Francis Bacon (both of 
imperishable fame) speaks in sundry letters, having been granted a Charter 
on July 1.5th, 1662, by Charles II, mathematical pupil of Hobbes, and 
having adopted as its title the name first applied to it by the celebrated 
diarist Evelyn — directed its inquiries, particularly, to what was then called 
the 'New Philosophy' or 'Experimental Philosophy' ' for the improving of 
natural knowledge by experiments'. True to its origin and history, the 
Royal Society still elects Princes of the Blood, and persons selected by the. 
Council from among men distinguished in walks of life other than Science ; 
whilst by the restrictions made during the presidency of Sir Joseph Banks, 
and subsequently, the number of Candidates recommended for election has 
been limited to fifteen annually. Concurrently with this restriction of the 
Fellowship, Science has grown enormously ; and as a consequence, other 
Scientific Societies have been established, some under the auspices of several 
Fellows of the Royal Society and by Royal Charter, some independently of 
either of these advantages, but all active in the promotion of special branches 


of Science. The Ro_yal Society is 144 years younger than the Royal 
College of Physicians of London, but it is the oldest exclusively scientific 
body in Great Britain, and one of the oldest in Europe. That it may 
continue in the successful performance of its various functions as the promoter 
of scientific investigations and researches, as the adviser of the Government 
in connexion with national scientific works, and as the administrator of 
Government grants and trust funds for experiments and for the publication 
not only of its own invaluable Transactions and Proceedings but also of 
scientific papers issued through other channels, is the earnest wish of the 
Royal Society of Medicine, which shares with other learned bodies the honour 
and special pleasure of taking part in the festivities of this Commemoration.

Royal Statistical Society, London 

To THE President, Council, and Fellows of the Royal Societv. — We, the 
President and Council, representing the general body of Fellows of the 
Royal Statistical Society, desire to present to the President, Council, and 
Fellows of the Royal Society on the occasion of the two hundred and fiftieth 
Anniversary of its foundation, our sincere congratulations and greetings. 
We are proud to claim association with your illustrious Society, not only 
because in the pursuit of exact knowledge we look to you for guidance and 
inspiration, but also because since the earliest days the Royal Statistical 
Society has received the active support of many who are eminent in Science. 
We recall with satisfaction that among the great names which adorn your 
roll are included those of many of our Presidents, while other Fellows of our 
Society intimately associated with our aims and activities, have added to 
their distinction as Statisticians the lustre of the Fellowship of the Royal 
Society. Among our Presidents the names of Lord John Russell, Lord 
Houghton, William Newmarch, Dr. William Farr, Dr. Guy, Lord Goschen, 
Sir Robert GifFen, Lord Avebury are prominent ; while our list of Treasurers 
includes Henry Hallam and George Richardson Porter. It is of interest also 
to record that Charles Richard Weld, the historian of the Royal Society, was 
at one time Assistant Secretary to the Royal Statistical Society. On the 
maintenance of your high traditions and the continuance of your labours 
depend in a large degree the future welfare and greatness of our nation. 
Now more than ever must your researches, by their breadth, by their 
penetration, by their originality, give an impulse to the force and variety 
of our national life. Great, however, as is your national mission, there is 
a greater still ; for Science recognizes no geographical frontiers nor is 
national advancement alone its incentive. Your high ideals touch the 
welfare of all mankind, and your labours are illumined by the whole 


firmament of Knowledge. It is because, in our more modest sphere of work, 
we too are guided by the same standards and inspired by the same ideals 
that we offer our sincere congratulations on this memorable occasion. 

Given under the Common Seal of The Royal Statistical Society, 11th 
July, 19m.

British Association for the Advancement of Science 

To the President and Council of the Royal Society. — We, the President 
AND Council of the British Association for the Advancement of Science, 
offer our cordial congratulations to the Royal Society on the occasion of the 
celebration of the two hundred and fiftieth Anniversary of the foundation of 
the Society. The British Association, since its birth in 1851, has been 
constantly in close relations with the Society. The great majority, not only 
of those who took the leading parts in the foundation of the Association, but 
of those who have filled its presidential chair, besides many others to whose 
earnest co-operation the success of its Annual Meetings has been due, have 
been Fellows of the Society. We would express the hope that the Society 
may continue to prosper, and may always maintain that pre-eminent position 
which is the fitting reward of its labours. Signed on behalf of the Council :

The Ashmolean Natural History Society of Oxfordshire sends heartiest 
congratulations to the Royal Society on the celebration of the 250th 
Anniversary of its foundation. It begs to express its profound admiration 
for the great part the Royal Society has played in the extensive development 
of Natural Knowledge, and in the enormous advancement of the beneficial and 
industrial Arts, during those 250 -years, and thanks the Royal Society for 
the stimulus and encouragement it has always afforded to other Societies, 
throughout the Empire, by its splendid example in the field of research. For 
these reasons the Ashmolean Natural History Society of Oxfordshire, thus 
named in memory of Elias Ashmole, one of the earliest Fellows of the Royal 
Society, desires herewith to offer its humble homage and greeting. 

ARTHUR A. RAMBAUT, President and Delegate. 

Society of Chemicai- Industry 

To THE President, Council, and Memhers of the Royal Society. — The 
President and Council of the Society of Chemical Industry offer to the 
Royal Society their most hearty congratulations on the attainment of the two 
hundred and fiftieth Anniversary of its foundation and have nominated to 

I 2 


represent them on this happy occasion Rudolph Messel, their President. At 
no time in the history of experimental science has there been any hard and fast 
line dividing science from its applications, and the President and Council of 
the Society of Chemical Industry recognize with pride that among the Fellows 
of the Royal Society have been found some of the most brilliant examples the 
world has seen of the genius which, while it seeks and grasps the highest 
generalizations, is at the same time intensely alive to the applications of 
science in arts and manufactures. As the oldest chartered scientific society in 
this country and the mother of many daughter societies, the Royal Society 
rouses the sympathy and admiration of all followers of applied science 
throughout the world. The Society of Chemical Industry cannot forget that 
it owed much of its early success to the timely support of Fellows of the Royal 
Society : the Right Honourable Sir Henry Roscoe, its first President ; Sir 
Frederick Abel, Sir Lowthian Bell, Sir William Perkin, Sir William Siemens, 
Dr. Angus Smith, Mr. Walter Weldon, Prof. A. W. Williamson, and Dr. 
James Young, its first Vice-Presidents ; and Capt. W. de W. Abney, Sir 
William Crookes, Dr. Peter Griess, and Dr. Hermann Sprengel, Members of its 
first Council. When the Society of Chemical Industry opened its doors to men 
of every country and every race, the Royal Society at once welcomed this 
manifestation of the brotherhood of Science, and marked its appreciation of the 
great importance of such international exchanges of courtesy and scientific 
opinion by the new departure of a reception to the Society and its members 
who had come across the sea. In industrial production the gain of one nation 
may be the loss of another, but the victories of science stand alone in that 
there is no enemy to vanquish but ignorance, and its conquests are for the gain 
and enrichment of the whole human race. The increased power over nature 
won by the work of Davy and Faraday, of Rumford, and of Rutherford gives 
no exclusive gain to any one country. The Royal Society and the Society 
of Chemical Industry have a common object in improving and increasing 
natural knowledge, and the future condition of mankind, both intellectually 
and materially, depends upon the gro\vth and activity of scientific Societies. 
The organized and systematic application of science to industry is still far 
from complete. The Society of Chemical Industry looks to the Royal Society 
to continue to bestow upon its work the interest and encouragement which 
have been so fully granted in the past. In wishing for the Royal Society 
continued and increasing prosperity, the President and Council trust that the 
cordial relations existing between the Societies may be maintained and result 
in a more extended co-operation.

Royal Society of Edinburgh 

To THE Royal Society of London. — The President and Fellows of the 
Royal Society of Edinburgh desire to offer their congratulations to the 
Royal Society of London upon the attainment of the two hundred and 
fiftieth Anniversary of its foundation. Founded for the purpose of ' further 
promoting by the authority of experiments the science of natural things and 
of useful arts', the Royal Society of London has with increasing zeal and 
power continued to fulfil its high calling, and commands in the world of 
scientific endeavour a position peculiarly its own. The Royal Society of 
Edinburgh recalls with pride and satisfaction that since its own foundation in 
1783 there has always existed between the two Societies a close association, 
based not only on community of aim and interests, but in great measure 
also upon community of membership. Scientific men of eminence have served 
on the Councils, and contributed to the publications, of both Societies ; 
and each Society can claim the late Lord Kelvin as one of the most renowned 
of its Presidents. At this time the personal connexion is happily exemplified 
by the fact that the distinguished President of the Royal Society of London 
has been a Fellow of the Royal Society of Edinburgh for fully half a century. 
May the important work which the Royal Society of London has achieved 
in the past be continued and extended, during many centuries to come, to 
the furtherance of natural knowledge and the progress of humanity.

The Royal Philosophical Society of Glasgow to the Royal Society of 
London for the Advancement of Natural Knowledge. — We, the Members 
of the Royal Philosophical Society of Glasgow, desire to express our gratifica- 
tion at the courteous invitation to take part in celebrating the two hundred 
and fiftieth Anniversary of the foundation of the Royal Society of London, 
and our heartiest congratulations on the uninterrupted and . pre-eminently 
fruitful activity of the Society over a period of such duration. Scientific 
Societies and Learned Bodies of all nations are bound and indebted in many 
ways to the Royal Society ; for leadership in scientific thought, for encour- 
agement of research, and for an unsparing hand in the dissemination of 
knowledge. Since its inception the history of the progress of the Royal 
Society has been largely the history of the advancement of science : the long 


Roll of its Fellows bears the names of almost all the illustrious men of two 
and a half centuries. Many of these we can recall whose names have adorned 
our own Roll, and we cherish with peculiar satisfaction the recollection that 
the late Lord Kelvin, during wellnigh sixty years, gave liberally of the 
offspring of his great genius to forward the interests of both societies. We 
also recall with pride that on the celebration of the Centenary of our Society 
in 1902 we were honoured by a cordial greeting from the Royal Society — the 
Mother and the Model of all the learned societies in the English-speaking 
world. It is our earnest hope that the Royal Society may long continue, 
with ever fresh ardour and increasing power, to carry on its great work for 
the advancement of knowledge.

Glasgow, this second day of July, Nineteen hundred and tzcelve.

The Royal Dublin Socikty to the Royal Society of London Greeting. — 
The President and Council of the Royal Dublin Society heartily join in 
congratulating the Royal Society of London on the attainment of the two 
hundred and fiftieth Anniversary of its foundation. Great has been the 
progress of science since the Society under Royal auspices undertook the task 
of improving natural knowledge, and the Fellows may well look with pride 
upon the conspicuous part they have taken in winning from Nature her well- 
guarded secrets. We earnestly hope that the Royal Society may continue its 
beneficent labours with increasing success, ever widening the bounds of know- 
ledge and extending man's control over Nature.
